Question

Reactions between atoms occur when:

A :an atom seeks to fill its outer shell of electrons
B :an atom seeks to balance its positive and negative charges
C :the reaction will result in paired electrons

Answer 1

A :an atom seeks to fill its outer shell of electrons

Step-by-step explanation:

Reactions between atoms occur due the desire of an atom to fill their outer shell electrons.

The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like those of the noble gases.

• The various interatomic interaction which leads to chemical reaction is in a bid for the atoms to be isoelectronic in the outer energy level with the noble gases.
• This is achieved by gaining, losing or sharing of electrons.
