Moving on, the Oxygen atom ( O 8) has six electrons in its outer shell. Therefore, it needs two … WebVandaag · So, is H2o (water) an ionic or a covalent compound? Yes, H2O (water) is a covalent compound because of the low difference in the electronegativity of Hydrogen (2.2) and Oxygen (3.44) atoms due to which the hydrogen and oxygen atoms share electrons with each other forming polar covalent bonds.
