no difference

lel jks

Ozone and oxygen are allotropes. (however the f*** you spell it).

- Ozone and oxygen differ in melting and boiling points with ozone being higher due to the presence of more intermolecular forces.
- Ozone is soluble in water as it is polar, and thus like dissolves like. Oxygen is non-polar and not soluble in water.
- Ozone is much more denser than oxygen in air because more mass per unit volume.
- Ozone is much more reactive than oxygen because of the presence of the single bond which only requires 100kJ/mol to be broken as opposed to the double bond in oxygen which requires 500.

Why is it harmful to humans

Ozone is harmful to humans because it is an irritant that causes respiratory problems and chest pains. May also cause fatigue.
