For electron in ' 2 s ' and ' 2 p ' orbitals, the orbital angular momentum values, respectively are :

Options

A2 ~h 2 and 0
Bh 2 and 2 ~h 2
C0 and 6 ~h 2
D0 and 2 ~h 2

Correct answer

D. 0 and 2 ~h 2

Step-by-step solution

aligned & Orbital angular momentum = ( +1) h 2 & For 2 ~s orbital : =0 & Orbital angular momentum =0 & For 2 p orbital : =1 & aligned Orbital angular momentum & = 1(1+2) h 2 & = 2 ~h 2 aligned aligned
