No, a Roman numeral should not be used when naming H2O. The chemical name for H2O is water, and it does not require a Roman numeral because it is a simple molecular compound. Roman numerals are typically used in naming ionic compounds to indicate the oxidation state of transition metals, which is not applicable in the case of water.

The Roman numeral after a metal name represents the oxidation state, or charge, of the metal ion in a compound. This notation is particularly used for transition metals, which can exhibit multiple oxidation states. For example, in iron(III) chloride (FeCl₃), the Roman numeral III indicates that iron has a +3 charge. This helps to clarify the specific ionic form of the metal present in the compound.
It is: 101 = CI
