When Iodine-131 emits a β particle (beta particle), what nuclide is produced? *

When Iodine-131 emits a β particle will produce Xe-131

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

So for reaction Iodine-131 :

Assuming atoms are shaped like spheres, what subatomic particles would be found in the center? What subatomic particles would be found around the perimeter? Center (nucleus) – protons & neutrons. Perimeter - electrons 3.

The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later. Protons and neutrons make up the nucleus of an atom.
