There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
carbon has 2 electrons in its first energy level and 4 in its secound energy level because carbons atomic number is 6. 4+2=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 2 electrons in its first energy level.
Oxygen has 6 electrons in its outermost energy level. This means it has a valence of 6.
More energy have the electrons in the second level of energy.
Oxygen has six valence electrons.
I donno,But there is 8 protons :D <3
More energy have the electrons in the second level of energy.
Oxygen has two electrons in the first energy level, and six electrons in the second energy level. The electron configuration is 1s2 2s2 2p4. Each level can hold a maximum number of electrons based on the formula 2n^2, where n is the energy level.

An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
