WebProtons and Neutrons in Magnesium. Magnesium is a chemical element with atomic number 12 which means there are 12 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to … WebSep 3, 2024 · 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 \(\left( +1 \right)\) and a mass of 1 atomic mass unit \(\left( \text{amu} \right)\), which is about \(1.67 \times 10^{-27}\) kilograms. The number of protons in an element can be found on the ...
