Hi i was wondering whether anyone understands radicals or has any resources that would help me understand it better?

A radical is a molecule of atom that is a fragment of an original molecule.  An example would be an O atom thathas been split up from an O2 molecule.

There's some stuff in the 'Atmosphere' unit in Chemical Storylines and there's also some stuff in Chemical Ideas

Radicals are any species with an unbonded pair of electrons.

It's easier to learn about them in a given context, such as in Atmospheres, where their properties (as a result of an unbonded electron from the photodissociation of ozone or dioxygen) allow them to react easily giving rise to the continuation of the ozone cycle. It's a similar situation with DNA and cancerous mutation so either would be a good place to start. As said above, look in Storylines or Chem ideas.

Radicals are atoms with unpaired electrons which makes them really reactive.

This is really weird but I think of radicals as single people and atoms with paired electrons as married people. The ones with unpaired electrons gets upset and desperately want a wife so try and react with everything. This also helps to explain why the attack bonds :-) x

 A:B → A o + B o Produces free radicals which have an unpaired electron and are very reactive
