Name the sub atomic particles in part Z of a boron atom give the relative charges of these sub atomic particles

Neutrons and protons

Explanation:

There are three fundamental subatomic particles, these are;neutrons protons and electrons.

Ernest Rutherford successfully showed that every atom does possess a central core that contain positively charged particles (protons) called the nucleus. Chadwick later discovered the existence of neutrons.

Both protons and neutrons are found in the nucleus. Z represents the nucleus of the boron atom and houses the neutrons and protons of the boron atom.
