Oxygen has 2 electrons in the first row S orbital, 2 electrons in second row S orbital, and 4 in the second row P orbital. The 2S and 2P tend to hybridize into an SP orbital with 6 electrons -- in this case it has two sets of pair-bonded electrons and two lone electrons for bonding therefore, 1s^(2)2s^(2)2p^(4) answer Solution Oxygen has 2 electrons in the first row S orbital, 2 electrons in second row S orbital, and 4 in the second row P orbital.
