Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.

No, BeF2 does not have a 3 charge. Beryllium fluoride (BeF2) is a neutral compound with a 2+ charge on the beryllium ion and a 1- charge on each fluoride ion, resulting in a net charge of 0.
The ionic compound formed between beryllium and selenium is beryllium selenide. Beryllium (Be) has a +2 charge, while selenium (Se) typically has a -2 charge. To balance the charges, one beryllium ion combines with one selenide ion, resulting in the formula BeSe.
The formula for a beryllium ion is Be2+. This indicates that the beryllium atom has lost 2 electrons, resulting in a 2+ charge.
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.

The charge of the compound BeF2 is neutral or 0. Beryllium (Be) has a +2 charge, and fluoride (F) has a -1 charge. Since there are two fluoride ions for every beryllium ion in BeF2, the charges balance out to give a neutral compound.
Beryllium has divalent cations Be2+.
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
The overall charge of a beryllium atom is neutral, meaning it has the same number of protons (+) in the nucleus as it does electrons (-) surrounding the nucleus. Beryllium has 4 protons and typically 4 electrons, resulting in a neutral charge.
Beryllium is an alkaline earth metal, so its charge will always be Be+2.
