Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
The chemical symbol of beryllium is Be; the symbol of the beryllium cation is Be2+.
Beryllium atom without 2 electrons; Be2+.

Beryllium(2+) ion sulfanediide is the name for the formula BeS.
Beryllium has divalent cations Be2+.
Electronic configuration of beryllium: 1s2.2s2.
mm
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.

Normally positive. However under the right conditions it could be either, as could anything.
