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?

Correct answer

10

Step-by-step solution

M n 2 + → 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
