a). 5
b).4
c).3
d).2
e).1

Answer 1

Given :

Chlorine's 3p sub level has 5 electrons in it.

To Find :

How many electron(s) more in the 3p sub-level to make it stable.

Solution :

Electronic configuration of Chlorine is :

[Ne] 3s² 3p⁵.

We know, p-orbit is stable with 6 electronic.

Therefore, to stable p-orbit 1 more electron is required in 3p sub-level.

Hence, this is the required solution.
