Beryllium has 2 core electrons. It has an atomic number of 4, which means it has a total of 4 electrons. The electron configuration is 1s² 2s², where the 1s² electrons are considered core electrons, while the 2s² electrons are valence electrons.
Beryllium has a total of four electrons. Its electron configuration is 1s² 2s², meaning it has two electrons in the 1s orbital, which are considered core electrons. Therefore, beryllium has two core electrons.
Beryllium (Be) has two valence electrons in its outer shell. To achieve a stable electron configuration, it typically forms compounds by sharing or losing these two electrons. Therefore, Beryllium does not need any additional valence electrons; it is stable with the two it has.
Silicon has a total of 10 core electrons and 4 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.
