. The number below the symbol is the atomic mass, which is the weight of the atom; this is the sum of the number of protons and neutrons. For example, hydrogen, the first element in the periodic table, has an atomic number of 1 and an atomic mass of 1.00794 atomic mass unit (amu)...
To determine the mass represented by one unified atomic mass unit (AMU), we can follow these steps:1. Understand the Definition of AMU: One unified atomic mass unit (1 AMU) is defined as one twelfth (1/12) of the mass of on

Physicists, desirous of greater precision, defined their atomic mass unit as 1/16th of the mass of the oxygen isotope 16 O. This made their atomic mass unit about 0.027% smaller than the chemical one. The symbol for both was amu (atomic mass unit). This was of course very confusing, ...
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....
