Question

16. Write the number of electrons present in a shell and mention the shell in F (Z=9).​

Answer 1

Explanation:

It depends on which shell you are talking about…

First shell contain 2 electrons

Second shell contains 8 electrons

Third shell contains 8 electrons

Fourth shell contains 18 electrons

Fifth shell contains 18 electrons

Sixth shell contains 32 electrons

Seventh shell contains 32 electrons

It may also be like 2, 8,18, 32 instead of the above rule… it's depends on the valency and which one has less free electrons

It's general formula is 2(n)^2
