Detailed explanation-1: -A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
Detailed explanation-2: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.
Detailed explanation-3: -The nucleus consists of 2 types of particles. They are neutrons and protons. The protons have unit positive charge and neutrons are neutral in charge.
Detailed explanation-4: -Nuclear charge refers to the positive charge on the nucleus.
