Atoms & their parts

The center of the atom is called the nucleus. The nucleus of most atoms is made up of two kinds of particles, protons & neutrons. Protons carry a positive (+) charge. Charge is an electrical property that can by either positive or negative.

Neutrons have no charge. The masses of protons and neutrons are measured in the atomic mass units (amu). Each proton or neutron has a mass of about 1 amu.

Electrons are subatomic particles that exist in an area outside the nucleus called the electron cloud. Electrons have a negative (-) charge. The mass of electrons is insignificant compared to the mass of protons & neutrons.
