Question
Element X is a metal with a valency 2, Y is 3 non- metal with a valency 3.
1) Write an equation to show how Y from an ion.
2) If Y is a diatomic gas, write an equation for the direct combination of X and Y to form a compound.

Solution
1) Y will form an anion by gaining 3 electrons.
The equation is given as Y + 3e- → Y3-
2) The equation for the direct combination of X and Y to form a compound is 3X + Y2 → X3Y2
