Question

The designation of the orbital n=4,I=3 is --

Answer 1

n= 4 that means principal quantum no is 4 and l= 3 means azimuthal quantum no is f. So orbital is 4f orbital

Answer 2

The quantum numbers are used here to determine the designation of the orbital i.e. the size of orbital and shape of orbital using n and l which are principal quantum number and angular quantum respectively.

The principal quantum number is used to determine the size of orbital using natural numbers.

So if n= 4 that means the size of orbital is 4.

The angikar quantum number is used to determine the shape of orbital.

If l=0 the orbital is spherical or s , l=1 the orbital is polar or p and if l=2 then the orbital is cloverleaf or d , if l=3 then it's for f .

Since here it's provided as l=3 so it's a cloverleaf.

Since here n=4, l=3

The designation of orbital is 4f.
