WebTherefore, the valence electrons of beryllium are two. The last shell of beryllium has two unpaired electrons, so the valency of beryllium is 2. The last electron of beryllium enters the s-orbital. Therefore, it’s an s-block element. To know these properties of beryllium one must know the number of electrons and protons of beryllium.
