Relative atomic mass (symbol: A r) or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.The atomic mass constant (symbol: m u) is defined as being 1 / 12 of the mass of a carbon-12 atom. Since both quantities in the ratio are masses, the resulting value is dimensionless; hence.

The atomic mass (m a) is the mass of an atom.Its unit is the unified atomic mass units (abbr. u) where 1 unified atomic mass unit is defined as 1 ⁄ 12 of the mass of a single carbon-12 atom, at rest. For atoms, the protons and neutrons of the nucleus account for nearly all of the total mass, and the atomic mass measured in u has nearly the same value as the mass number.

Gold (symbol Au, atomic number 79) has it’s name from the Latin "Aurum", which means shining dawn. What formed this association is not known, because gold has been known to man since antiquity or about 5,500 years.

An element is an actual physical substance that cannot be broken down into a simpler form, and is capable of an independent existence as observable matter. As such, the concept of the element is a macroscopic one that relates to the world that we can observe with our senses. The atom is the microscopic realization of this concept; that is, it is the actual physical particle that is unique to.
