Oxygen has an electron configuration of 1s2 2s2 2p4. In its outer valence shell it has 6 electrons. Two hydrogen molecules with one electron each bind to two of the electrons. We are than left with two lone pairs of electrons (4 electrons).

oxygen have 6 electrons in its outermost shell because it have 8 electrons
It's electronic configuration is - 2,6
2 electrons are present in 1st shell and remaining 6 are in 2nd shell.
So oxygen cannot have 4 electrons in outermost shell .
Hope it will help you

brother ,,,second shell is 2s2 (1s2 2s2 2p4 ) so it can hold maximum 2 elctrons
plzz mark as brainliest
no second shell can hold maximum 8 electrons and 3rd also
second shell is 2s
so it will be 2s6
thanks lakshya
