Question

How many orbitals are there in n shell ?

Answer 1

Dear student,

Sub-shell	No. of orbitals	Maximum no. of electrons
s	1	2
p	3	6
d	5	10
f	7	14

The number of orbitals are depends on the value of principle quantum number 'n'
For n shell the number of orbitals are = $n^2$
If n = 1 then, $1^2$ = 1
n = 2 $2^2$ = 4
Likewise, we calculated for different values of n
