When do ions form?

When an atom loses or gains electrons to create a full outershell

What does it happen with?

A metal and a non-metal

Hydrogen charge

H⁺

Hydroxide charge

OH^-

Ammonium charge

NH₄⁺

Carbonate charge

CO₃^2-

Nitrate charge

Sulfate charge

SO₄^2-

Ionic bond diagram

Dot and cross diagram

What is an ionic bond?

An electrostatic attraction between oppositely charge ions

Properties of Ionic Compounds

High melting and boiling points because the ionic bonds are strong and require lots of energy to break them

Do ionic compounds conduct electricity when solid and why?

They don’t because the ions are not free to move but do when molten (liquid) or dissolved in water because the ions are free to move
