Atomic Number
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
Atomic Weight
The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, atomic mass is often expressed in the non-SI unit dalton – equivalently, unified atomic mass unit. 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state
