Question

3 multiple choice 6 points which of the following types of elements require a roman numeral in the name? transition metals non - metals main block metals all metals

Explanation:

Transition metals often have multiple oxidation states. To distinguish between different compounds of the same transition metal with different oxidation states, a Roman numeral is used in the name to indicate the oxidation state of the transition metal. Non - metals do not typically use Roman numerals in this way. Main block metals (like alkali and alkaline earth metals) usually have a single common oxidation state and do not require Roman numerals. Since not all metals (as main block metals don't need it) require Roman numerals, the answer is based on the property of transition metals having variable oxidation states.

Answer:

Transition metals
