Quizplus · Accepted Answer

An oxygen atom with atomic number 8 has 6 valence electrons. It needs 2 electrons to complete its octet. Therefore, it can make 2 covalent bonds with hydrogen, with each hydrogen atom providing 1 electron to share with oxygen. So, the maximum number of covalent bonds that an oxygen atom with atomic number 8 can make with hydrogen is 2, which is option B.
