2 1 H

Explanation:

We must remember that a nuclear equation is only said to be balanced when the mass and charges on both sides of the nuclear reaction equation correspond.

If we look at the nuclear equation; the total mass on the right hand side is 4 units while the total charge on the right hand side is two units.

This implies that the missing particle must be 2 1 H
