How did ozone form

WebOzone is measured as the total amount that is present in a column of overlying atmosphere in Dobson units. One Dobson unit can be thought of as the amount of ozone that would be present if it formed a layer 0.01mm thick at average sea-level pressure and temperature. A typical Dobson reading for the ozone layer is about 300 Dobson units, meaning ... WebAllotropy. Oxygen has two allotropic forms, diatomic (O 2) and triatomic (O 3, ozone).The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for the paramagnetism of oxygen. The three atoms in the ozone molecule do not lie along a straight line.. Ozone may be produced from oxygen …

As the images show, the word hole isn’t literal; no place is empty of ozone. Scientists use the word hole as a metaphor for the area in which ozone concentrations drop below the historical threshold of 220 Dobson Units.
