How to Find Atomic Mass - 3 Different Methods - BYJU

The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total mass of at… WebThis chemistry video tutorial explains how to calculate the number of protons, neutrons, and electrons in an atom or in an ion.
