I might be wrong but: I know that beryllium has two electrons total and the first ring can only fit two electrons so the number of valance electrons is most likely two. Please correct me if I'm wrong.
The first ring of the electron cloud holds two electrons. All rings following it hold eight.
Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.

Classic answer is to "satisfy" a full valance ring of electrons.
Ionic type of bonding is highly favored among the ionic species, where one atom has tendency to donate electrons and the other has tendency to accept electrons in order to attain a stable atomic coniguration with a filled outer shell of electrons.

The number of electrons in Sulfur atom is 16. Therefore there are 6 electrons in its 3rd ring.
Two electrons.
Helium has only two electrons with one ring (or energy level). Both the electrons are in the one and only energy level / shell / ring.
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
Eght electrons are held on the third ring. Eight on the second, two on the first. 1:2 2:8 3:8 4:18
The outer (valance) ring is full.
