Splet21. sep. 2024 · Main Difference – Atomic Number vs Mass Number. Atoms are composed of electrons, protons, and neutrons.Protons and neutrons together make the nucleus of an atom. When measuring the mass of an atom, we actually measure the mass of the nucleus. That is because the mass of an electron is negligible when compared to a proton or a … SpletMass Number = # of Protons + # of Neutrons. Mass Number = 1 + 2. Therefore, this particular atom of hydrogen will have a mass number of 3. Note that the mass number …

Spletproton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10 −27 kg, which is 1,836 times the mass of an electron. SpletMercury's atomic mass is 200.59, but we can round that to 201 (this is known as the mass number). This is a tally of the total number of particles in an atom's nucleus, so an 'average' atom of mercury contains 201 particles in its nucleus. We know that 80 of those particles are protons. The rest must be neutrons.
