Answer 2

$\sf\underline{Question}$

What is the valency of magnesium in Mg₃N₂

$\sf\underline{Answer}$

• Let the valency of Magnesium in Mg₃N₂ be 'x'
• We know that, valency of nitrogen = - 3
• 3x + 2(-3) = 0
• 3x - 6 = 0
• 3x = 6
• x = $\sf\frac{6}{3}$
• x = 2
• There fore, the valency of magnesium in Mg₃N₂ is "2"

$\sf\underline{Note}$

• Dont write the valency as "+2" ,. its a common mistake which we do. Valency dont have any signs
• If oxidation state is asked, then the answer will be "+2"
