Which of the following orbitals are possible ? (2s,1p,3f,2p)

Text Solution

Verified by Experts

2s and 2p are possible .
1p is not possible because first orbit contains only s-orbital but no p - orbital .
3f is not possible because third orbit contains three orbitals only . They are 3s ,3p and 3d .
