1. a triton
2. a beta particle
3. a proton
4. an alpha proticle

Answer 1

X should be equivalent to an alpha particle, which can be thought of as a helium nucleus. We represent the alpha particle as ⁴₂He, and when balancing nuclear reactions, we make sure that both the atomic numbers and atomic masses are equal on both sides.
