Passage / Comprehension

The general electronic configuration of outer most and penultimate shell is given as (n -1)s²(n - 1)p⁶(n 1)d^xns² . Then for an element with n = 4 and x = 7

The number of protons present in the divalent cation of the element of above configuration is

Answer:

27.00

Solution:

$3 s^{2} 3 p^{6} 3 d^{7} 4 s^{2}$

$M : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{7} 4 s^{2}$

$Z = P = 27$
