GCSE Bonding: Ionic, Covalent & Metallic

Why do bonds form?

• To fill the outer shell of electrons

• to release energy stored in the bonds

• because whenever you mix two chemicals, there will be a reaction

• because of attraction

A solid substance is an excellent conductor of electricity.

Bonding is....

• ionic, because the outer electrons are shared between atoms

• covalent, because the outer electrons can move

• metallic, because the outer electrons are stationary

• metallic, because the outer electrons can flow through the substance
