However, I want to learn it before my classmates to be more succesful at this topic. Beta decay is somewhat more complex than alpha decay is. Beta negative decay is more penetrating than alpha decay because the particles are smaller, but less penetrating than gamma decay. The number of protons found in the nucleus of an atom. Types of radioactive decay include alpha, beta, and gamma decay. process by which the nucleus of an unstable atom loses energy by emitting radiation equations. These points present a simplified view of what beta decay actually is: 1) A neutron inside the nucleus of an atom breaks down, changing into a proton.
