Answer:

Alpha particles, Beta particles, gamma rays, and neutrons

Explanation:

usually there's 2 ways radioactivity occurs: radioactive decay and ionization. radioactive decay breaks down the nucleas over time transforming the protons and neutrons into smaller particles alpha and beta with a little gamma radiation (gamma radiation is what was decaying). ionization is when the nucleas ejects neutrons as it's form of decay, leaving radioactive isotopes.

It is really easy if you look up an electron configuration table (one that looks like a periodic table) and then just go down the rows left to right, top to bottom, and just stop when you get to where the element is on the table.
