Explanation:
Compounds are made up of elements that are chemically joined. Like elements, compounds have properties that allow us to identify them. Learn about physical properties, like color, odor, melting point and boiling point, as well as chemical properties in this lesson.

Chemical compound is a chemical substance made up of atoms of more than one element by chemical bonding. Two atoms of the same element bound in a molecule do not form a chemical compound because it requires two different elements.
There are four types of compounds, depending on how the constituent atoms are put together:
The molecule held together by covalent bonds
Ionic compounds are held together by ionic bonds.
Unmetallic compound are held together by metal bonds
Certain complexes held together by covalent bonds
A chemical formula specifies the number of atoms of each element in a compound molecule, it USES standard abbreviations and numerical subscript of chemical elements. For example, the formula of a water molecule is h2o which binds two hydrogen atoms with one oxygen molecule. Many chemical compounds have a unique kyc number identifier allocated by chemical abstract service. More than 350,000 chemical compounds (including those containing chemicals) have been registered for production and use.
A compound can be converted into a different chemical structure by interaction of another chemical compound by chemical reaction. In this process, relations between atoms break into compounds of interaction, and new bonds are formed.
