The atomic number definition is based on the number of protons in an atom. Protons are positively charged particles in the nucleus of atoms. The atomic number is based solely on the number of protons in an atom. In contrast, atomic mass is based on the number of protons and neutrons in ...
The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different ato...
