Question

Select 3 evidences that show that the oxygen atoms bond covalently to form oxygen molecule
1.oxygen is nonmetal 2.insoluble in water
3.electrons are completely transferred from one oxgen atom to the other
4.highly soluble in water
5.oxygen atoms share 2 pairs of electrons

Answer 1

Explanation:

polar covalent bonds

The bonds between oxygen and the hydrogen atoms within the water molecule are polar covalent bonds,i.e., the electrons are not shared equally between oxygen and hydrogen. Oxygen has a higher affinity for electrons than does hydrogen
