Oxygen is 8 so,electronic configuration of oxygen is 2,6.there is need to be atmost 2 electrons are present in first shell of an atom .and in second shell there are 8 electrons are needed to form stable octate.but oxygen only have 6 electrons in 2nd shell.so,oxygen needs 2 electrons to complete its octate.HENCE,THE VALENCY OF OXYGEN IS 2

the electron configuration of oxygen is1s^2.2s^2.2p^4.
when oxygen formed some elements sometime it has two pairs of lone pair .remaining electron is used to make that element that's why oxygen valence is 2
