Understand the basic properties of subatomic particles: Electrons, protons, neutrons, and positrons are all subatomic particles, each with distinct charges.
Recall that electrons have a negative charge. This is a fundamental property of electrons, which are found in the electron cloud surrounding the nucleus of an atom.
Remember that protons have a positive charge. Protons are located in the nucleus of an atom and are responsible for the positive charge of the nucleus.
Neutrons are neutral particles, meaning they have no charge. They are also located in the nucleus of an atom alongside protons.
Positrons are the antimatter counterparts of electrons and have a positive charge. However, in the context of typical atomic structure, protons are the positively charged particles commonly referred to.
