Beryllium
Beryllium has 4 electrons. It has 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
No. Germanium in the ground state has 32 electrons, 4 of these are valence electrons which can participate in chemical reactions. Perhaps that is where you are getting confused.
A metalloid with 4 electrons, such as silicon, has 2 core electrons. In the case of silicon, the electron configuration is 1s² 2s² 2p², where the 1s² electrons are the core electrons, while the 2s² and 2p² electrons are considered valence electrons. Thus, it has 2 core electrons and 4 total electrons.
Lead has 4 valence electrons.
Silicon has a total of 10 core electrons and 4 valence electrons.

4 electrons, 2 valence electrons
4 electrons
Helium-4 has 2 electrons.
C has 4 electrons O has 6 electrons==> O2= 6*2=12 electrons CO2= 4+12 =16 electrons

Si ( Silicon) is in the same group as carbon. As a consequence it has four outer electrons. These four electrons covalently bond to other atoms, in the same manner as carbon. Si does NOT gain or lose electrons in the sense of ionisation.

Thus, it has 2 core electrons and 4 total electrons.
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
