The mass number represents the weight of the protons and neutrons in Atomic Mass units (AMUs). One AMU is equal to one proton or neutron.
The average mass of all isotopes of the element - apex.
Scientists use the symbol "u" to represent atomic mass unit.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
Atomic Mass or mass no
mass.
m can either represent mass or moles, depending on the context.
The mass of an object can be expressed in mass per unit or in total mass. Total mass represent the full amount.
M stands for the mass.
The average total mass of its neutrons,protons and electrons
