If $M n^{2 +}$ has 'X' number of unpaired electrons and 'Y' other positive oxidation states than +2. What is the sum of X + Y here?

Answer:

10.00

Solution:

$M n^{2 +} \to (A r) 3 d^{5}$

unpaired $e^{-} (X) = 5$

Mn can show +3, +4, +5, +6 and +7 oxidation states also other than +2.

Y = 5

X + Y = 5 + 5 = 10
