Beryllium and sulfur will form a ____ bond.

Beryllium and sulfur will form an ionic bond.

Here's the step by step explanation:

1. Beryllium (Be) is a metal from group 2 (alkaline earth metals) of the periodic table. It has 2 electrons in its outermost shell and tends to lose these electrons to achieve a stable electron configuration.

2. Sulfur (S) is a non-metal from group 16 of the periodic table. It has 6 electrons in its outermost shell and tends to gain 2 electrons to achieve a stable electron configuration.

3. When beryllium and sulfur come into contact, beryllium will lose its 2 electrons and sulfur will gain these 2 electrons. This transfer of electrons from beryllium to sulfur leads to the formation of ions.

4. Beryllium becomes a positive ion (Be2+) and sulfur becomes a negative ion (S2-). The attraction between these oppositely charged ions results in the formation of an ionic bond.

So, beryllium and sulfur will form an ionic bond.
