Is electrons the mass number
WebJun 2, 2014 · The mass number tells us the nucleus contains 19 particles in total. Since 9 of these are protons, the other 10 are neutrons. We call it the mass number because virtually all the mass in an atom comes from the protons and neutrons - electrons weigh about 1/2000th of the mass of a proton or neutron. Answer link WebAtomic Number – Protons, Electrons and Neutrons in Oxygen. Oxygen is a chemical element with atomic number 8 which means there are 8 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) …
