Question Question 3(2015)
A metal ‘X’ has valency 2 and a non-metal ‘Y’ has a valency 3. If ‘Y ’ is a diatomic gas, write an equation for the direct combination of X and Y to from a compound.
X (metal) has a valency 2, hence,
X - 2e- ⟶ X2+
Y (non metal) has a valency 3. hence,
Y + 3e- ⟶ X3-
Therefore, the two combine as :
3X + 2Y ⟶ X3Y2
