In this true/false item, we need to assess the statement about Type II cations and their naming conventions.
Option 1: True. The claim is that Type II cations form more than one possible charge, so the charge is included in the name, written after the element name in roman numerals inside parentheses and without spaces. This matches the standard convention for naming cations of transition metals (Type II): the roman numeral indicates the oxidation state and appears as a suffix in parentheses directly after the element name, with no spaces (for example, iron(II) chloride or copper(II) sulfate).
Option 2: False. This option would assert a negation of the statement in Option 1. Since the established convention indeed uses roman numerals in parentheses immediately after the element name to denote the charge, this option contradicts the standard naming rule and is therefore incorrect.
To ensure understanding, consider why the rule matters: Type II cations can exhibit multiple oxidation states, so appending the charge clarifies which form of the cation is involved in the compound. The lack of a space between the element name and the parentheses is a conventional formatting detail, not a semantic change, which is why the phrase "without spaces" is a correct descriptor here.
If you encounter a scenario where the roman numeral is outside the parentheses or there is a space before the parentheses, those would be signs that the naming convention described is not being followed, and such phrasing would be inaccurate in the context of Type II cation naming.
