Here are the essential concepts you must grasp in order to answer the question correctly.
Cations and Anions
Cations are positively charged ions formed when an atom loses one or more electrons, while anions are negatively charged ions created when an atom gains electrons. In the context of the periodic table, elements in red typically represent transition metals that can form cations with varying charges, whereas blue elements often represent nonmetals that can form anions.

Ionic Compounds
Ionic compounds are formed through the electrostatic attraction between cations and anions. The overall charge of the compound must be neutral, which means the total positive charge from the cations must balance the total negative charge from the anions. The formulas of these compounds reflect the ratio of cations to anions needed to achieve this balance.

Naming Ionic Compounds
The naming of ionic compounds involves stating the name of the cation first, followed by the name of the anion. For cations that can have multiple charges, such as transition metals, the charge is indicated using Roman numerals in parentheses. For example, FeCl2 is named iron(II) chloride, indicating that iron has a +2 charge in this compound.
