BeF2

Answer 1

The correct formula for the compound formed when beryllium (Be) combines with fluorine (F) is BeF2.

Beryllium has a +2 charge when it forms ions, and fluorine, being in group 17, has a -1 charge. To balance the charges, two fluorine ions are needed for each beryllium ion, resulting in the formula BeF2.
