Whichof the following orbitals are possible ?
IP, 2s, 2p and 3 f

Text Solution

Verified by Experts

For 1p oribit n = I , l = 1
For possible orbital `l lt n ,` which is true is this case.Hence it is possible.
For 2p orbital `n = 2, l = 1 `
For possible orbitla `l lt n,` which is true in this case, hence it is possible.
For 3f orbital `n = 3, l = 3.`
For possible orbitla `l lt n.` but here `n = l.` Hence it is not possible.
