Atoms of the same element consist of the same atomic A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion (thermonuclear weapon). Both reactions release vast quantities of energy from relatively small amounts of matter.Nuclear weapon
Isotope
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos and topos, meaning "the same place"; thus, the meaning beh…
Do atoms of the same element have the same chemical properties?
Atoms of the same element, with the same electron configurations (i.e. an atom is not bonded or ionized), have the same chemical properties. However, atoms of the same element may have different physical properties. Isotopes of the same element may have a different number of protons in their nuclei, which means they have different masses.
What is the difference between isotopes and atoms?
Isotopes have the same atomic number but different atomic masses. Atoms of an element share that element's chemical and physical properties, such as boiling point, melting point and stability. An element is the simplest form of matter and cannot be broken down further by chemical means.
What is it called when two atoms of the same element?
Atoms of the same element that have a different number of neutrons are called isotopes. Isotopes have the same atomic number but different atomic masses. Atoms of an element share that element’s chemical and physical properties, such as boiling point, melting point and stability.
What do atoms of an element have in common?
Atoms of an element share that element's chemical and physical properties, such as boiling point, melting point and stability. An element is the simplest form of matter and cannot be broken down further by chemical means.
Do atoms of the same element have the same properties?
- Atoms of a given element are identical (meaning they have the same mass and properties). - Atoms retain their identity in all chemical reactions. � This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a reaction.
What property is the same for each atom of an element?
Atomic Number and Mass Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.
What properties do elements in the same group share?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
What are the 4 properties of atoms?
The nuclear properties (atomic mass, nuclear cross-sections) of the element are determined by the number of protons (atomic number) and the number of neutrons (neutron number)....Therefore, there are various non-equivalent definitions of atomic radius.Van der Waals radius. ... Ionic radius. ... Covalent radius. ... Metallic radius.
What are the 4 properties of elements?
These properties include color, density, melting point, boiling point, and thermal and electrical conductivity. While some of these properties are due chiefly to the electronic structure of the element, others are more closely related to properties of the nucleus, e.g., mass number.
What do all elements have in common?
The common feature is that the atoms of all elements consist of electrons, protons, and neutrons.
What are 2 things elements in the same group have in common?
The vertical columns are called groups. The elements which are in the same groups have the same number of valence electrons (i.e same number of electrons in the outermost shell). Also they possess almost similar properties. Yes there are also few exceptions in the elements of d-block and f-block.
Do elements in the same group share physical properties?
So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.
What are the properties of an elements?
All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements.
Which property of elements is same in a period of periodic table?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
Do all atoms of the same element have the same size?
Colm - So Les all atoms of the same material are the same size but different items of different materials are different sizes. So for instance the single smallest item is hydrogen and a single hydrogen is about one twentieth of a nanometre across.
What property of an atom determines which element it is quizlet?
Remember that the number of protons in the nucleus determines an element's identity.
What are the atoms of an element that have the same number of neutrons?
Atoms of an element usually have the same number of neutrons as protons. Atoms of the same element that have a different number of neutrons are called isotopes. Isotopes have the same atomic number but different atomic masses. Atoms of an element share that element's chemical and physical properties, such as boiling point, ...
What are the elements that are arranged in different molecular formations called?
Atoms of the same element that are arranged in different molecular formations are called allotropes. Allotropes may have different physical appearances and different characteristics such as electrical conductivity. For example, a diamond, coal and soot all are ...
How many elements are there in the periodic table?
An element is the simplest form of matter and cannot be broken down further by chemical means. There are 118 known elements, arranged in the periodic table in order of atomic number. Of these elements, only the first 98 are naturally occurring.
Do all atoms of the same element have the same number of protons?
All atoms of the same element have the same number of protons in the nucleus and consequently have the same atomic number. All atoms of the same neutral element have the same number of electrons as well. Atoms of an element usually have the same number of neutrons as protons.
What are the physical properties of atoms of the same element?
Atoms of same element have the same physical 3D properties. They also share chemical properties. Conductivity, magnetic, electronegativity, bonding angles.
Which elements have the same chemical properties?
Elements that are above and below each other in the same vertical column of the periodic table have the same chemical properties because they have the same outer electron shell properties. For example, lithium, sodium, and potasium are all highly reactive metals with one electron in the outer shell. Likewise, helium, neon, argon, and xenon are all chemically inert and do not form compounds because they all have full outer electron shells.
What is the difference between isotopes and elements?
But then there are different isotopes of the same element (same atomic number but different number of neutrons), which usually show the same chemistry (exceptions are slightly different
How many protons does an element have?
First, some definitions. When we say element, what we’re really talking about is the number of protons in the nucleus of an atom. If it has six protons, for example, it’s a carbon - no matter what else it has.
Do protons have a positive charge?
Yet nature seems to cram a number (even a large number) of protons together inside the rather small volume of the nucleus.
Is chlorine the same as isotopes?
Isotopes have slightly different properties, but we’re talking on a level that generally only matters to chemists (kinetic isotope effects, for example). They’re basically the same. Ions typically have radically different properties. For example, chlorine is a green gas that will kill you if you inhale it. Chloride - the anion (-1 charge) of chlorine - is found in saltwater, pool water, and most food. That being said, chloride is derived from chlorine, so the argument can be made that they’re one and the same thus react identically.
Can two atoms be different?
It is possible to summarize all these different ways of differing by saying two atoms are different when they are in different quantum states, but I am not sure how useful that is, especially since it blurs the difference between permanent differences such as atomic number and transitory ones such as energy levels.
