Beryllium has divalent cations Be2+.
The Be++ ion.
In most cases, yes beryllium has 4 protons and 4 electron, but this is only beryllium in neutral form. There is also an ion of beryllium though which has 4 protons and 2 electrons.
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.
an atom which readily losses or gains electrons to attain stability forms an ion.
Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
Beryllium is the only stable light metal with a relatively high melting point.
Xenon does not readily form an ion.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.

Beryllium. And it's an element, not a chemical.
+2
Beryllium lose electrons (2).
NO!!! Fluorine is an elemental gas , with the formula of 'F2'. Structurally (F-F ). However it does form the ion , the fluoride ion , 'F^-'.
