Describe the relation of the atom's electron configuration to its position in the periodic table:

Solution Preview

The electronic configuration of Mg is

Mg: 1s2 2s2 2p6 3s2

The orbital box diagram is in the attached figure.

Mg is in the 2nd group of the periodic table.It has 12 electrons and hence is the 12th element in the periodic table. We can see from the electronic configuration that it can easily lose its two 3s electrons to become a stable element with completely filled ...

Solution Summary

The solution is given in 200-300 words with the orbital box diagram attached.
