Difference Between Atoms and Molecules

DIFFERENCE BETWEEN ATOMS AND MOLECULES

Even though atoms are the basic components­ of molecules, they differ in many aspects when compared to the molecules. Table 7.5 consolidates the major difference between ­atoms and molecules.

Difference between atoms and molecules

Atom

1. An atom is the smallest particle of an element.
2. Atom does not exist in free state except in a noble gas.
3. Except some of noble gas, other atoms are highly reactive.
4. Atom does not have a chemical bond.

Molecule

1. A molecule is the smallest particle of an element or compound.
2. Molecule exists in a free state.
3. Molecules are less reactive.
4. Atoms in a molecule are held by chemical bonds.
