In chemistry, an atomic mass unit or AMU is a physical constant equal to one-twelfth of themassof an unboundatomofcarbon-12. It is a unit ofmassused to expressatomic massesandmolecular masses. When the mass is expressed in AMU, it roughly reflects the sum of the number of protons and n...
It also describes the atomic mass unit and explores why an atom needs neutrons. Atomic mass definition and atomic mass formula The atomic mass is the mass of an atom, including its protons, neutrons, and electrons. However, because an electron is 1,836 times less massive than a proton, ...

AMU, it roughly reflects the sum of the number of protons and neutrons in the atomic nucleus (electrons have so much less mass that they are assumed to have a negligible effect). The symbol for the unit is u (unified atomic mass unit) or Da (Dalton), although AMU may still be used....
