Why have the atomic mass unit taken so complicated as 1/12 of c12 atom? It could have been equal to 1 neutron or proton.

Expert Answer:

The mass of a single atom is subsequently small its unit is measured by means of a unit known as the atomic mass unit (a.m.u). It is also called a universal mass unit, which is based on the weight of one carbon atom. Thus one a.m.u is equal to 1/12 the mass of a carbon atom, or the mass of one hydrogen atom. The explanation for the mass of an atom is easier when expressed by means of atomic mass unit. Atomic mass ranges from 1.008 a.m.u for hydrogen to 296 a.m.u for the element of ununquaternium.
