Mass number, atomic number, atomic number, isotope, charge

Explanation:

The total sum of the protons and neutrons in the atomic nucleus is called mass number. It is approximately equal to the mass of the atom.

The number of protons that are present in the nucleus of an atom is called atomic number. It is represented by letter Z.

Each chemical element has a unique atomic number because of the presence of same type of atoms in an element.

The isotope is a variant of a particular chemical element. All isotopes have similar protons but different neutrons in numbers. Hydrogen can have different isotopes depending upon the number of neutrons.

An atom that have more electrons than protons will have a negative charge because electrons are responsible for imparting negative charge.
