The beryllium atom has 4 electrons and the valence is 2.
Beryllium has 2 valence electrons.
2 valence, 4 electrons total
Beryllium has a 2s2 number of valence electrons
I might be wrong but: I know that beryllium has two electrons total and the first ring can only fit two electrons so the number of valance electrons is most likely two. Please correct me if I'm wrong.
For example calcium and magnesium.
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.

Beryllium has two valence electrons.
In an electrically neutral atom, the number of electrons is the same as the number of protons. Since the number of protons is the atomic number of an atom, and Beryllium has an atomic number of 4, this means that Beryllium has 4 protons in its nucleus. As mentioned previously, if the atom is electrically neutral, then Beryllium will also has 4 electrons.

Beryllium has one valence shell containing two electrons.
