Electrons form a spinning cloud around the nucleus. 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.

Protons and neutrons each weigh 1 atomic unit, while electrons are virtually weightless. Answer and Explanation: Two atoms with the same atomic number but different mass numbers are called b. isotopes To have the same atomic number, the...
Number of electrons is equal to atomic number Z . Number of neutrons = Mass number (A) - Atomic number (Z).
