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 unpaired electrons in the divalent cation of the element in isolated gaseous state is

Question diagram: The number of unpaired electrons in the divalent cation of t

Answer:

3.00

Solution:

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

$M^{2 +} : 3 s^{2} 3 p^{6} 3 d^{7} 4 s^{0}$

The number of unpaired $e^{⊖} = 3$
