Question

1. Write a short note on electronic theory.​

Answer 1

Explanation:

This theory explains about the cause of chemical reaction/combination on the basis of valence shell electron (i.e electron present in the outermost orbit) & tendency to lose or gain an electron. The outermost shell of an atom is called valence shell &electron present in it is called valence electron.

Answer 2

Answer:

Explanation:

According to the electronic theory of valency, when atoms combine to form molecules, the electrons in the outermost shells of the atoms tend to acquire inert gas structure (1s2 or s2p6), which has maximum stability and minimum energy. The atoms after bond :formation contain eight electrons in 'their outermost shells.
