Which of the following describes the electron sharing between two oxygen atoms? each oxygen shares one electron with the other.
each oxygen shares six electrons with the other.
each oxygen shares eight electrons with the other.
each oxygen shares two electrons with the other

I believe each oxygen shares 2 elections with the other.

It is 4.92 e-4 sorry if i am wrong

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
