Ionic Bonding

The video explains how sodium and chlorine, two dangerous elements, form sodium chloride, a harmless compound we consume daily. It describes the process of metal and non-metal atoms forming compounds through electron transfer, resulting in ionic bonds. The video highlights the properties of ionic compounds, such as high melting and boiling points, due to the strong attraction between ions.

What transformation occurs when sodium and chlorine chemically bond together?

• They produce a metallic alloy.

• They become a harmless compound.

• They create a flammable liquid.

• They form a toxic gas.

What do metal atoms typically need to do to achieve stability?

• Gain electrons to fill their outer shell.

• Lose electrons to have a full outer shell.

• Remain unchanged to maintain stability.

• Share electrons with other metal atoms.

How do non-metal atoms generally achieve stability?

• By losing electrons.

• By gaining electrons.

• By sharing protons.

• By remaining neutral.

What is the result of the attraction between positive and negative ions?

• An ionic bond.

• A metallic bond.

• A hydrogen bond.

• A covalent bond.

Why do ionic compounds have high melting and boiling points?

• Because of weak intermolecular forces.

• Due to their ability to conduct electricity.

• Due to the strong attraction between ions.

• Because they are composed of light elements.
