The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
If one atom of oxygen has six electrons in its outer level, then there would be two electrons that are not in pairs. Oxygen atoms typically have a configuration of 2 electrons in the 2s orbital, and 4 electrons in the 2p orbital, with two of those 4 electrons being unpaired.

There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
In the very first shell it has 2 and then it has 6 (in the second shell). =)
Oxygen has six valence electrons.
Oxygen has 6 electrons in its outermost energy level. This means it has a valence of 6.
In oxygen, the third energy level can hold a maximum of 18 electrons. However, oxygen only has 8 electrons in total, so only 2 electrons are found in the third energy level.
Oxygen has 8 total electrons, with 2 in the innermost energy level. Therefore, oxygen has 6 core electrons.
I donno,But there is 8 protons :D <3

Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
Two electrons can be housed in the first energy level.
The first energy level can hold up to 2 electrons.
