Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
How many electrons will Beryllium gain or lose when forming an ion?
Beryllium will lose 2 electrons when forming an ion because it has 4 valence electrons and tends to reach a stable electron configuration by losing electrons to achieve a full outer shell.
Will Se lose or gain electrons and how many?
Se will gain electrons
How many electrons does Si gain or lose?
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.
