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.

When we are naming elements with a transition metal why do we need to write a Roman numeral in the middle?

When naming compounds that include transition metals, a Roman numeral is used to indicate the oxidation state or charge of the metal ion. This is necessary because transition metals can have multiple oxidation states, and the Roman numeral helps to specify which one is present in the compound. For example, in iron(III) chloride, the Roman numeral III indicates that iron has a +3 charge. This distinction is crucial for accurately conveying the compound's chemical composition and properties.
