In the vertical columns of the periodic table, as the atomic numbers increase:

the number of electron shells increase

The elements with the highest ionization energy and thus the most unreactive are:

noble gases

The atomic number of the atom which does not usually form compounds is:

18

The first four ionization energies for an imaginary element, X z are E 1 = 102 kcal, E 2 = 186 kcal, E 3 = 4,021 kcal, and E 4 = 4,862 kcal. The number of valence electrons most probable as indicated by this ionization data is:

2

The electron configuration notation for Na is:

1s ² 2s ² 2p ⁶ 3s ᴵ
