Will Se lose or gain electrons and how many?
Se will gain electrons
How many electrons does lithium lose or gain to achieve a stable octet configuration?
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
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.
