Respuesta :
I think each oxygen atom can share two electrons with the other so that each atom has eight valence electrons. The oxygen atoms forms each two covalent bonds since two pairs of electrons are shared in an oxygen molecule. The sharing of electrons helps the atom to achieve stable structures.
Answer:
The correct answer is "the double covalent bond theory".
Explanation:
Each oxygen atom has 6 valence electrons in the outermost layer. To have greater stability you need to gain two electrons per atom. Therefore two oxygen atoms form a double bond by sharing two electrons each, completing the Lewis octet to acquire greater stability.
Have a nice day!
