CHEMICAL BONDS

By Michael sulak

Ionic bonds

Atoms want to combine together because they have a lower potential energy than when they are alone. They want to combine because they would have a lower potential energy and nature likes that because it's more stable than being alone.

Metal and nonmetal elements bonding together. (They lose or gain electrons)

Traits: looks powdery, dissolves in water, high melting point, conducts as a liquid and in water  but doesn't as a solid.

EXAMPLE: Salt

Covalent bonds

Nonmetal and nonmetal elements bonding together. (They share electrons)

Traits: looks powdery, sometimes dissolves in water and sometimes doesn't, low melting point, NEVER conducts electricity.

EXAMPLE: Water (H2O)

Metallic bonds

Metal and metal elements joining together.

Traits: looks shiny, doesn't dissolve in water, high melting point, always conducts electricity.

EXAMPLE: bronze (Copper and other metals)
