Question

Find out the valency of the atom represented by fig (a) and (b) ​

Answer 1

Fig a: 0

Fig b: 0

Explanation:

Fig a is argon,

In an atom, the number of electrons on the outer shell is the number of valence electrons. Fig one shows eight, so argon has eight valence electrons. Since it already has full number of electrons in the previous shells and has 8 in the last one, there is no resson to loose or gain electronsl Thus, argon has 0 valency.

Fig b is neon,

We also notice that neon has 8 valence electrons, so since it has 8 in the last one, there is no reason to loose or gain electrons. Thus, neon also has 0 valency.

Answer 2

Answer:

The answer is zero
