Ionic Bonds

An ionic bond is a type of chemical bond that occurs between a metal and a non-metal. This bond is formed through the transfer of electrons from the metal to the non-metal, resulting in the formation of ions with opposite charges.

Formation of Ionic Bonds

When a metal atom interacts with a non-metal atom, the metal atom tends to lose one or more electrons from its outer shell, while the non-metal atom tends to gain those electrons. This transfer of electrons leads to the formation of positively charged metal ions and negatively charged non-metal ions. The attraction between these oppositely charged ions results in the formation of an ionic bond.

Properties of Ionic Compounds

• Ionic compounds typically form crystalline structures.
• They tend to have high melting and boiling points.
• They are often soluble in water and conduct electricity when dissolved.

Examples of Ionic Compounds

Some common examples of ionic compounds include sodium chloride (NaCl), potassium chloride (KCl), and calcium oxide (CaO).

Study Guide

Here are some key points to remember about ionic bonds:

1. Define an ionic bond and explain its formation.
2. Describe the properties of ionic compounds.
3. Provide examples of ionic compounds and their chemical formulas.
4. Explain how ionic compounds conduct electricity in their molten or dissolved state.

Be sure to practice writing the chemical formulas for common ionic compounds and understand the concept of ion formation and electron transfer.
