Cobalt has 1 less proton than Nickel. The extra mass comes from having different isotopes that have more neutrons. Elements on the periodic table are ordered according to the number of protons an atom of the element has in its nucleus. This is called the atomic number. Cobalt has 27 protons while Nickel has 28 - thus Cobalt is first on the table. Atomic mass, however, has to do with protons How to calculate atomic weight percentage for chemical.
(1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article. Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm 3), Atomic Weight. Atomic weight Atoms Mass percent; Nickel: Ni: 58.6934: 1: 64.0058: Oxygen: O: 15.9994: 2: 34.8950: Hydrogen: H: 1.00794: 1: 1.0992
At its 1989 meeting, the Commission changed its recommended value for the atomic weight of Ni to Ar (Ni) = 58.6934 (2) based on recent mass-spectrometric determinations. The excellent agreement between the average of the chemical values and this new determination illustrates the remarkable accuracy of the determinations of Baxter and associates. Atomic Number of Nickel.
