Question

(i) Total number of sub shells in the ‘n’th energy level is $n^2$
(ii) The maximum number of electrons in a subshell is obtained using the equation (4l + 2)
(iii) The values of orbital angular momentum of an electron in the orbitals 1s, 3s, 3d, 2p respectively is 0, 0$\sqrt{6}h$, $\sqrt{2}h$
(iv) The quantum number not obtained from Schrodinger’s wave equation is ‘$m_l$’. The correct option is

• A. Only i& ii
• B. Only iii & iv
• C. Only ii & iii
• D. i, ii, iii, iv

Answer 1

The correct option is C Only ii & iii

Statement (i) $\Rightarrow$ The number of subshells in the ‘n’th energy level is ‘n’

Statement (iv) $\Rightarrow$ The quantum number not obtained from Schrodinger’s wave equation is ‘$m_s$’ or spin quantum number.
