When an unstable nucleus decays, it changes into a different one and throws out a particle. In an alpha decay it loses a helium nucleus; in a beta decay a neutron turns into a proton and an electron is fired out. The two numbers always balance across the equation. Set the daughter nucleus so the top and bottom both add up.

After this decay, the proton number will be:
The unstable nucleus is buzzing. Predict, set the daughter nucleus, then check.

nucleon numbers (top) balance??
proton numbers (bottom) balance??
The equation must balance: the top numbers add up on both sides, and so do the bottom numbers.
