Formed when 2 atoms share electrons

In general, this type of bond will form a compound with a high melting point.

Kerosene (C₁₂H₂₆) is used in oil lamps.

The attraction between 2 oppositely charged ions

Sucrose (C₁₂H₂₂O₁₁) is commonly used in baking.

People often use sodium bromide (NaBr) to sanitize their hot tubs.

Magnesium oxide (MgO), like magnesium chloride (MgCl₂), chloride, is used to maintain adequate magnesium in the body.

This type of bond will form a compound that can conduct electric current when dissolved in water.

Ozone (O₃) can form when emissions from vehicles react with heat & sunlight.

Cow farts, which release methane (CH₄), are a source of global warming.

Glucose (C₆H₁₂O₆) is produced by plants during photosynthesis.

Carbon dioxide (CO₂) is the 4th most abundant gas in the earth’s atmosphere.

We commonly use sodium chloride (NaCl) to season our food.

Ammonia (NH₃) is found in many household cleaning solutions.

In general, this type of bond will form a compound that cannot conduct electric current when dissolved in water.

Usually forms between a metal and a nonmetal

Acetic acid (C₂H₄O₂) is commonly found in vinegar.

We can’t live without dihydrogen monoxide (H₂O).

In general, this type of bond will form a compound with low melting and boiling points.

In general, this type of bond will form hard, brittle crystals.

Usually forms between 2 nonmetals

Calcium oxide (CaO), also known as lime, gives off a white light when heated. Theaters once used special lamps to focus this bright light on a single actor. So…the expression “in the limelight” describes a person who receives favorable attention.

Dusting sodium bicarbonate (NaHCO₃) lightly under arms absorbs odors rather than  covering them up, as some deodorants do.

Calcium chloride (CaCl₂) can be used to melt ice.
