Only method to classify molecules is whether they are homonuclear, they consist of only one element, like H2, O2, O3, P4, N2, and S8; heteronuclear, consist of more than one element, like NO2, CH4, PCl5, CO, and C6H12O6.
Compounds are characterized by their chemical formula. A chemical formula is an information or detail about the parts of atoms that create a specific chemical compound.
Compounds can be categorized into two types, molecular compounds, and Salts. In molecular compounds, atom combines each other via covalent bonds. In salts, it is bounded together with ionic bonds. These are the two kinds of bonds out of which each compound is made of.
|Compound Name||Compound Formula|

|1||Definition||A molecule is a group or cluster of two or more atoms held together by chemical bonds.||A compound is a substance or material which is formed by two or more different types of elements which are combined chemically in a fixed proportion.|
|2||Relatedness||All molecules are not compounding.||All compounds are molecules.|
|3||Example||An example of a molecule is an ozone molecule.||An example of a compound is table salt or sea salt (sodium chloride).NaCl|
|4||Structure||Molecules are just a group of atoms which are bonded by a strong force.||All compounds are definite matter in their complete shape.|
|5||Visibility||Molecule cannot be seen or watched with the naked eye as they are at atomic level.||A compound can be easily seen via naked eye.|
|6||Stability||A molecule can be very unstable.||A compound is always stable as it has a physical form.|
