Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.


How many more electrons does silicon need in order to have a stable octet?

Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.


Can carbon expand its octet beyond four valence electrons?

No, carbon cannot expand its octet beyond four valence electrons.


How many electrons must an atom have to fulfill the octet?

2 or more electrons, because Oxygen already has 8.


Do metals gain electrons to have full octet?

No, metals tend to lose electrons to achieve a full octet.


How many Valence electrons in a stable octet?

8 valence electrons


In order to form an octet an atom of selenium will lose or gain?

An atom of selenium will gain two electrons to achieve an octet because it has six valence electrons in its outer shell. By gaining these two electrons, selenium will have a total of eight electrons in its outer shell, fulfilling the octet rule.


Why are what octet's rule?

Octet Rule: In order for atoms to become more stable, they will take electrons, lose electrons, or share electrons so that their outer shell/level will contain eight electrons and be complete.
