What are Ionic Bonds?

Ionic bonds are a type of chemical bond that occurs between two oppositely charged ions. These ions are formed when one atom transfers one or more electrons to another atom. The atom that loses electrons becomes a positively charged ion, known as a cation, while the atom that gains electrons becomes a negatively charged ion, known as an anion. The attraction between these opposite charges results in the formation of an ionic bond.

Formation of Ionic Bonds

Ionic bonds are typically formed between metals and non-metals. Metals tend to lose electrons to achieve a stable, noble gas electron configuration, while non-metals tend to gain electrons to achieve the same configuration. For example, in the formation of sodium chloride (NaCl), sodium (a metal) donates an electron to chlorine (a non-metal), resulting in the formation of Na+ and Cl- ions, which then form an ionic bond due to their opposite charges.

Properties of Ionic Compounds

Ionic compounds have several characteristic properties, including:

• High melting and boiling points
• Crystalline structure
• Conductivity in molten or aqueous state
• Solubility in water

Study Guide

When studying ionic bonds, it's important to understand the following key concepts:

1. How ions are formed through the gain or loss of electrons
2. The role of metals and non-metals in ionic bond formation
3. The properties of ionic compounds
4. Examples of common ionic compounds and their constituent ions
5. How to write the chemical formula for an ionic compound based on the charges of the ions
