Explanation:
Detailed explanation-1: -The nucleus (or center) of an atom is made up of protons and neutrons.
Detailed explanation-2: -Protons and neutrons are composed of two types: up quarks and down quarks. Each up quark has a charge of +2/3. Each down quark has a charge of-1/3. The sum of the charges of quarks that make up a nuclear particle determines its electrical charge.
Detailed explanation-3: -Neutrons are located in the nucleus with the protons. Along with protons, they make up almost all of the mass of the atom. The number of neutrons is called the neutron number and can be found by subtracting the proton number from the atomic mass number.
