Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...
Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All copper atoms have 29 protons. All helium atoms ...
