It depends on what element you start with.
No, carbon cannot expand its octet beyond four valence electrons.
the same number of electrons needed to fill their octet, the same number of valence electrons,
The octet rule.
six valence electrons.....It only requires two more to complete octet....
Oxygen needs to gain 2 electrons to reach an octet, as it has 6 valence electrons in its outer shell and requires a total of 8 electrons to have a stable octet configuration.
8 valence electrons
No, carbon cannot expand its octet beyond four valence electrons.
the same number of electrons needed to fill their octet, the same number of valence electrons,
An octet
it has a full octet
The octet rule.

Oxygen needs to gain 2 electrons to reach an octet, as it has 6 valence electrons in its outer shell and requires a total of 8 electrons to have a stable octet configuration.
Octet
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
Yes, neutral unbonded atoms can complete a valence octet by gaining or losing electrons to achieve a stable electron configuration with 8 valence electrons. This stability is known as the octet rule, which applies to many elements in the periodic table.
Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
