Which are compounds but not molecules?
All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.
Is a molecule an element?
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.
Is NaCl ionic or molecular?
Sodium Chloride (NaCl) is a pure ionic compound and not a covalent compound. The two atoms transfer their electrons to form ions, Na+ and Cl-.
What defines a molecular compound?
A molecular compound consists of molecules whose formula represents the actual number of atoms bonded together in the molecule. The atoms are joined to give a definite shape which is defined by the angles between the bonds and by the bond lengths.
Is NaCl ionic or covalent?

For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons.
What is the covalent bond?
Covalent bonds are the attractive forces between the positively charged nuclei of the bonded atoms and one or more pairs of electrons that are located between the atoms. Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them.
How many electrons does a neutral atom of calcium have?
For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca 2+.
What is an ionic compound?
What is Ionic Compound? Ionic compounds can be defined as: The crystalline solids formed by neatly packed ions of opposite charge. Ionic compounds are usually formed when metals react with non-metals. In other words, ionic compounds held together by ionic bonds as classed as ionic compounds.
What is the structure of an ionic compound?
Ionic Compound Structure. The structure of an ionic compound depends on the relative sizes of the cations and anions. Ionic compounds include salts, oxides, hydroxides, sulphides, and the majority of inorganic compounds. Ionic solids are held together by the electrostatic attraction between the positive and negative ions.

Why do ionic compounds have a high melting point?
Ionic Compounds: Due to the strong attractive forces between the positive and negative ions in an ionic compound, a lot of energy is required to break the ionic bonds between the oppositely charged ions. So they have a high melting and boiling point.
How are compounds formed?
A compound is formed when two or more elements go on to combine together to form a new substance. The chemical and physical properties of the compound that is eventually formed are different from those of the constituent elements. Most of the substances found in nature exist in the form of compounds, rather than as free elements.
Why are ionic compounds hard?
Ionic Compounds: Ionic compounds are very hard because of their closely-packed lattice structure and the ionic bonds between the charged ions. They are very brittle, and it is difficult to bend them. Molecular Compounds: The solid forms of molecular compounds are generally very soft and brittle.
