How are the elements variable valency named?
Elements with variable valency are typically named using Roman numerals to indicate their oxidation states in a compound. For example, iron can have a valency of +2 or +3, and in compounds, it may be referred to as iron(II) for the +2 state and iron(III) for the +3 state. This nomenclature helps clarify which specific ion is present in the compound. Additionally, some elements may use traditional names, such as "cuprous" for copper(I) and "cupric" for copper(II).
What are the following elements that are in the same period as magnesium?
Magnesium is in Period 3 of the periodic table.
