Detailed explanation-1: -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: -Protons. Positively charged particles that are contained in the nucleus of the atom (the centre) they have a mass of 1amu (atomic mass unit).
Detailed explanation-3: -Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.
Detailed explanation-4: -Nuclear charge refers to the positive charge on the nucleus.
Detailed explanation-5: -The nucleus contains protons, which have a positive charge equal in magnitude to the electron’s negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.
