What is meant by ionic substances?
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For example, KCl, an ionic compound that contains K+ and Cl- ions, is named potassium chloride.
What types of substances are ionic substances?
Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion.
How do you identify an ionic substance?
Classifying compounds as ionic or covalent
- If a compound is made from a metal and a non-metal, its bonding will be ionic.
- If a compound is made from two non-metals, its bonding will be covalent.
What are 5 ionic compounds?
Ionic bond examples include:
- LiF – Lithium Fluoride.
- LiCl – Lithium Chloride.
- LiBr – Lithium Bromide.
- LiI – Lithium Iodide.
- NaF – Sodium Fluoride.
- NaCl – Sodium Chloride.
- NaBr – Sodium Bromide.
- NaI – Sodium Iodide.

What are ionic compounds Class 11?
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.)
What are anions and cations?
Cations are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). Anions are negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons).
