Small covalent molecules are held together by
Webb22 juli 2024 · Water (H 2 O) is a covalent compound because the bond forms between two hydrogens and one oxygen are covalent in nature. The covalent bond is formed due to the sharing of electron occurs between hydrogen and oxygen atoms in order to complete their octet shell and hence attains stability.
