검증된 단계별 안내1
Identify the elements involved: hydrogen (H) and oxygen (O). Both are nonmetals.
Recall that when two nonmetal atoms combine, they typically form covalent bonds by sharing electrons.
Understand that in a water molecule (H_2O), each hydrogen atom shares one electron with oxygen, allowing oxygen to complete its octet.
Recognize that ionic bonds usually form between metals and nonmetals, which is not the case here.
Conclude that the bond type in water is a covalent bond, where electrons are shared between hydrogen and oxygen atoms.
