Question

Why orbitals like 1p, 2d and 3f are not possible? Explain?

Answer 1

■ The sublevels are calculated from the formula ( l=0 to n-1 )

● So , if n = 1 ☆( l=0 to 1-1 = 0 ), l=0 its mean S sublevel only

So its impossible to have 1p in frist level

● In n=2 ☆ the possible values of L are

( 0 as S & 1 as P ) so 2d is not possible

● In n=3 ☆ the possible values of sublevels are ( 0 as S , 1 as P & 2 as d) , so 3f not possible

Hope the answer is useful , have a nice day
