Today, we learnt about the ozone layer.
- blue and purple – least ozone; green, yellow and red – more ozone
- 90% of ozone occurs in the stratosphere – measured in Dobson Unit (DU)
- Isotopes
- 1A – Alkali metals; 2A – Alkali earth metals; 7A – Halogens; 8A – Noble gases
- Bonding
- E=hv
- Microwaves, Infrared, Visible, UV, X-rays, Gamma rays
- UV radiation/light
- CFCs – chlorine destroy ozone
- Skin cancer
- Ozone hole
