What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

How do you name ionic compounds containing a metal with a fixed charge?

Back

For metals with a fixed charge, the name of the metal is followed by the name of the nonmetal with its ending changed to '-ide'. For example, NaCl is named sodium chloride.

What is the naming convention for ionic compounds with transition metals?

Back

For transition metals, the charge of the metal ion is indicated by Roman numerals in parentheses after the metal's name. For example, FeCl₂ is named iron(II) chloride.

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons from one atom to another, resulting in charged ions, while covalent compounds are formed by the sharing of electrons between atoms.

What is the significance of the Roman numeral in the name of an ionic compound?

Back

The Roman numeral indicates the oxidation state (charge) of the metal ion in the compound.
