DIFFERENCE BETWEEN ATOMS AND MOLECULES - DEFINITION
Atoms Molecules
Smallest particle of atom Smallest particle of compound
It may or may not exist independently It always exist independently
It may or may not have properties of matter It always possess properties of matter
Atoms may be molecules due to independent existence But molecule cannot be that atom
An element is made up of atoms of one kind A molecule can exists by itself and retains all the properties of the element or compounds
Examples of atoms are O, N Examples of molecules are O
2
,N
2
Atoms have no further kind Molecules are further divided into homo-atomic and hetero-atomic molecules
MOLECULES OF ELEMENTS - EXAMPLE
concept
A molecule is the fundamental building block of a substance which can normally exist on its own. When two or more atoms of same type combine, the molecule of an element is obtained.
Examples of molecules of element are Hydrogen, Oxygen etc.
