How exactly do radicals form and how would we know if we are given a radical? Are there specific elements that are more likely to form radicals? And how would you go about the process of drawing a radical?

I'm not completely sure of the formation of radicals, but in lecture Professor Lavelle mentioned that radicals are highly reactive and only exist for a short time. He said that they are often involved in reactions which I believe means that radicals are often intermediates in a series of reactions.

You can figure out if a single atom is a radical by writing out the electron configuration. For molecules, if any molecule has an odd number of electrons (uneven number), then it is likely a radical as there must be an unpaired electron on that molecule. However there are molecules that have two unpaired electrons and therefore would have an even number of electrons but still be radicals. One would then need to use molecular orbital theory to determine if that molecule has them all paired or two unpaired electrons.

What is molecular orbital theory?

Radicals are molecules that have an odd number of electrons. They are very unstable and they can only exist for a relatively short time period.

Radicals are unpaired electrons.

Radicals are when an element has a single electron un paired. This happens when the number of electrons is an odd number.

Radicals are unequal pairs of electrons that can be found when you are given a compound. For instance, the compound OF has 13 valence electrons. This is an unequal pair of electrons because 13 does not make an equal pair of electrons since it is an odd number, one electron will be left by itself.
