Subatomic particle that has a positive charge. Also it’s found nucleus of an atom.

A central region of a atom and it’s made up of protons and neutrons.

Has no charge and is found in the nucleus of an atom.

Has negative charge and also is a subatomic particle.

In a atom there is a high probability of finding electrons.

Electron founded in the outside shell of an atoms. It also determines the atoms chemical properties.

Electron found in the outer shell and determines the elects chemical property

The number of protons and electrons in a atom?

Proton plus nuetrons
