An organic compound is any compound containing carbon, aside from some simple ones discovered before 1828. There are three classes of organic mineral: hydrocarbons (containing just hydrogen and carbon), salts of organic acids, and miscellaneous.
Are all minerals are chemical compounds?
Although most minerals are chemical compounds, a small number (e.g., sulfur, copper, gold) are elements. Minerals combine with each other to form rocks. For example, granite consists of the minerals feldspar, quartz, mica, and amphibole in varying amounts.
Which minerals are not compounds?
1 Answer. Diamond and graphite are both forms of the element carbon and contain no other elements.
Are minerals a compound or element?
Minerals are made up of chemical elements. A chemical element is a substance that is made up of only one kind of atom. Have you heard of oxygen, hydrogen, iron, aluminium, gold and copper? These are all chemical elements.
Is gold a compound?
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form.
What is the difference between minerals and compounds?
Explanation: A compound is more than one element that are joined by chemical bonds, and can only be separated by chemical means, but a mineral is simply a solid form of a element or a compound.
Are minerals mostly compounds?
“A mineral is a naturally occurring chemical compound, usually of crystalline form and abiogenic in origin. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.
Are rocks a compound?
Rocks are an example of a mixture of solids. Minerals combine physically to make rocks, but elements combine chemically to make minerals.

What is not a mineral?
Minerals – Mineral is a naturally occurring inorganic solid with definite chemical composition and a crystalline structure. Coal is not a mineral because it does not qualify to be one. A mineral is made of rocks. Coal is non-living and made up of atoms of elements.
Are very few minerals compounds?
Each mineral has its own properties because all minerals are compounds. A mineral always contain certain elements in definite proportions. Each compound has its own properties which usually differ greatly from the properties of the elements that form it.
What compounds are not found in a Nonsilicate mineral?
What compound of elements will you never find in a nonsilicate mineral? Nonsilicate minerals never contain compounds of silicon bonded to oxygen. Each type of mineral is characterized by a specific geometric arrangement of atoms, or its crystalline structure.

Another common mineral is quartz, or silicon dioxide. Its crystals have a specific hexagonal shape. Coal is a mineral composed entirely of carbon, originally trapped by living organisms ...
How are minerals formed?
Minerals are substances naturally formed in the Earth. Minerals are typically solid, inorganic, have a crystal structure and are formed by geological processes naturally. A mineral may consist of a single chemical element or a compound more usually.
What is a crystal?
Mineral Crystal. A crystal is a homogeneous body which has been bounded by smooth plane faces. Crystals usually possess certain elements of symmetry which may be categorized into three groups: planes of symmetry, axes of symmetry and centre of symmetry.
What is the plane of symmetry of a crystal?
The plane of symmetry of a crystal divides it into two parts each of which is similar to the other. The axis of symmetry of a crystal is an axis about which the rotation of the crystal makes it occupy the same position more than once during its rotation through 360 o degrees.

Why do we need minerals?
The body uses minerals to perform many functions — from building strong bones to nerve impulse transmission. Some minerals also create hormones or hold a regular heartbeat.
What is the group of minerals that are naturally occurring?
There exists a subset of minerals which are the naturally occurring elements. This group of minerals is usually called the native elements group and includes the substances which are mostly pure elements that occur naturally and meet all the other mineral definition characteristics. These are miner
What is a compound made of?
A compound is a substance that is made up of more than one element.
What are the two groups of minerals that can be substituted for each other?
For lots of minerals, ions can swap out easily if they have the same ionic radius and charge. One such pair is iron and magnesium, which are very different chemically but can easily be substituted in minerals. In many cases we have group names, with pure compounds being called end members. One such group is olivine, which consists of the end members fayalite (Fe2SiO4) and forsterite (Mg2SiO4). The generic mixture is simply called olivine and the formula is written (Mg,Fe)2SiO4, where the elements in parentheses indicate substitution. One of the most important series is the plagioclase feldspars, a mixture of albite (NaAl3Si3O8) and anorthite (CaAl2Si2O8). The series is subdivided into albite, oligoclase, andesine, labradorite, bytownite and anorthite depending on the relative proportions.
What are the natural elements?
These are minerals such as Iron, Copper, Gold, Silver, Carbon, Lead , ect. These substances are not compounds, but are minerals when they occur naturally.
How do mountains form?
Mountains form in different ways. Mountains are formed by massive movements of the earth's crust. Earth's crust is made up of huge slabs called tectonic plates, which fit together like a jigsaw puzzle. When two slabs of the earth's crust push against each other, the crust gets pushed upwards, forming mountains. Many of the greatest mountain ranges of the world have formed because of enormous collisions between continents.
What are elements made of?
Elements are the substances made of only one kind of atoms. There are very few elements which are obtained in nature as mineral.
What metals are uncombined?
Gold, sulfur diamonds, and some other metals can be found in their uncombined (uncharged and not in compunds), elemental form.
What is the chemical makeup of a mineral?
Since a mineral has a definite composition, it can be expressed by a specific chemical formula. Quartz (silicon dioxide), for instance, is rendered as SiO 2, because the elements silicon (Si) and oxygen (O) are its only constituents and they invariably appear in a 1:2 ratio. The chemical makeup of most minerals is not as well defined as that of quartz, which is a pure substance. Siderite, for example, does not always occur as pure iron carbonate (FeCO 3 ); magnesium (Mg), manganese (Mn), and, to a limited extent, calcium (Ca) may sometimes substitute for the iron. Since the amount of the replacement may vary, the composition of siderite is not fixed and ranges between certain limits, although the ratio of the metal cation to the anionic group remains fixed at 1:1. Its chemical makeup may be expressed by the general formula (Fe, Mn, Mg, Ca)CO 3, which reflects the variability of the metal content.
What are the minerals that are produced by the human body?
Minerals also are produced by the human body: hydroxylapatite [Ca 5 (PO 4) 3 (OH)] is the chief component of bones and teeth, and calculi are concretions of mineral substances found in the urinary system.
How are minerals formed?
mineral, naturally occurring homogeneous solid with a definite chemical composition and a highly ordered atomic arrangement; it is usually formed by inorganic processes. There are several thousand known mineral species, about 100 of which constitute the major mineral components of rocks; these are the so-called rock-forming minerals.
What is an artificial mineral?
A mineral, which by definition must be formed through natural processes, is distinct from the synthetic equivalents produced in the laboratory. Artificial versions of minerals, including emeralds, sapphires, diamonds, and other valuable gemstones, are regularly produced in industrial and research facilities and are often nearly identical to their natural counterparts.
Is a mineral a crystalline solid?
Minerals display a highly ordered internal atomic structure that has a regular geometric form. Because of this feature, minerals are classified as crystalline solids. Under favourable conditions, crystalline materials may express their ordered internal framework by a well-developed external form, often referred to as crystal form or morphology. Solids that exhibit no such ordered internal arrangement are termed amorphous. Many amorphous natural solids, such as glass, are categorized as mineraloids.
Is a mineral a homogeneous solid?
By its definition as a homogeneous solid, a mineral is composed of a single solid substance of uniform composition that cannot be physically separated into simpler chemical compounds. Homogeneity is determined relative to the scale on which it is defined. A specimen that appears homogeneous to the unaided eye, for example, ...
Is glass a mineraloid?
Many amorphous natural solids, such as glass, are categorized as mineraloids. Schematic representation of the structure of pyrite (FeS 2) as based on a cubic array of ferrous iron cations (Fe 2+) and sulfur anions (S − ).
How are minerals distinguished?
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety .
What crystals sit on a bed of albite?

What is the classification of minerals?
Classification of minerals. Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides ). Several reasons justify use of this criterion as ...
Which group of minerals has high densities?
The gold-group minerals crystallize in the isometric system and have high densities as a consequence of cubic closest packing. In addition to the elements listed above, the platinum group also includes rare mineral alloys such as iridosmine.

Which semimetals have a structure type distinct from the simple-packed spheres of the metals?
The semimetals antimony, arsenic, and bismuth have a structure type distinct from the simple-packed spheres of the metals. In these semimetals, each atom is positioned closer to three of its neighbouring atoms than to the rest. The structure of antimony and arsenic is composed of spheres that intersect along flat circular areas.
What are the properties of gold, silver, and copper?
Gold, silver, and copper are members of the same group (column) in the periodic table of elements and therefore have similar chemical properties. In the uncombined state, their atoms are joined by the fairly weak metallic bond. These minerals share a common structure type, and their atoms are positioned in a simple cubic closest-packed arrangement. Gold and silver both have an atomic radius of 1.44 angstroms (Å), or 1.44 × 10 – 7 millimetre, which enables complete solid solution to take place between them. The radius of copper is significantly smaller (1.28 Å), and as such copper substitutes only to a limited extent in gold and silver. Likewise, native copper contains only trace amounts of gold and silver in its structure.
What are the three groups of metals?
The most common native metals, which are characterized by simple crystal structures, make up three groups: the gold group, consisting of gold, silver, copper, and lead; the platinum group, compose d of platinum, palladium, iridium, and osmium; and the iron group, containing iron and nickel-iron. Mercury, tantalum, tin, and zinc are other metals ...
How many elements are there in nature?
Native elements. Apart from the free gases in Earth’s atmosphere, some 20 elements occur in nature in a pure (i.e., uncombined) or nearly pure form. Known as the native elements, they are partitioned into three families: metals, semimetals, and nonmetals.
