unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons and neutrons of the nucleus account for nearly all of the tot...
1 All of the atoms in alkali metals have one electron in their outer electron shells. To become stable they have to give off one electron to elements with seven electrons in their outer shell making it eight, also stable. Then they become single charged positive ions (cations). Melting ...

Atomic mass is the relative weight of the protons and neutrons in an atom. Remember, atoms are composed of protons, neutrons, and electrons. Electrons are much smaller than either protons or neutrons, so we consider their mass negligible. The unit used for atomic mass is atomic mass units (...
