Which is the correct answer, n=4(where n is the number of shells). Then number of subshells and electrons present in atom are
A 16,32
B32,16
C32,32
D16,16



Answer is A

Answer 1

Hey Mate...

We get the no of electrons from the formula 2n^2..

Where n is no of shell

2*4^2

2*16

32..
so no of electrons is 32

Now no of subshells = no of electrons /2

32/2


16..

Hence option "" A"" is correct.


Hope it helps
