Note: All compounds are molecules, but not all molecules are compounds.

Answer 2

Difference between atom, element and compound, molecules is as follows -

• Atoms comprise of proton, neutron and electron are the smallest particle.
• Specific type of atom is called element, where particular number of protons, neutrons and electrons are present.
• Molecules are formed by combination of same or different type of elements.
• Compounds are formed by chemical bonding of different and multiple elements.
