Question

Column-I: Subshell Column-II: Number of spherical nodes Column-III: Radial plot

The only correct combination for the last electron of $C{l}^{-}$ is:

• A. (IV) (i) (R)
• B. (IV) (iv) (P)
• C. (III) (iii) (Q)
• D. (II) (ii) (P)

Answer 1

The correct option is A

(IV) (i) (R)

$C{l}^{-}:1s^{2}2s^{2}2p^{6}3s^{2}3p^6$

For last electron, subshell is 3p.

Number of spherical nodes $=n-l-1$

= 3 - 1 - 1 = 1
