Calculate the average mass of a Mg atom. Answer: 24.31 amu We can also do variations of this type of calculation, as shown in the next example. Example 5.2
WebbElectrons in successive atoms on the periodic table tend to fill low-energy orbitals first. Thus, many students find it confusing that, for example, the 5p orbitals fill immediately after the 4d, and immediately before the 6s.The filling order is based on observed experimental results, and has been confirmed by theoretical calculations.
