Beryllium has divalent cations Be2+.
Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
Electronic configuration of beryllium: 1s2.2s2.
Beryllium(2+) ion sulfanediide is the name for the formula BeS.
Beryllium has the electronic configuration 2, 2, so it is likely to lose two electrons, giving it the Helium configuration. However, in practice, beryllium compounds have a high degree of covalent character as the beryllium ion is small and very polarising.
Beryllium has divalent cations Be2+.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
Beryllium. And it's an element, not a chemical.

Normally positive. However under the right conditions it could be either, as could anything.
Beryllium is the only stable light metal with a relatively high melting point.
