radicals

Postby tatianatumbling_1J » Sat May 12, 2018 4:12 pm

can someone elaborate on radicals? The TA went over them really quickly and I don't remember how she defined them.

A radicals is a atom/molecule with a single unpaired valence electron. They contain an orbital valence orbital that only has one electron, not two. Radicals are highly reactive.

They are electrons that are not used while making bonds

These atoms or molecules are found whenever the number of valence electrons is odd, leaving one unpaired valence electron.

I don’t think that is totally true. Lone pairs also are electrons that are not used “while making bonds.” But radicals are more specific, like what Emily said above, that radicals involve a single, unpaired valence electron.

What I meant was that they are not used up in a bond (the lines we draw to represent a bond). They are not shared or transferred when they are shown as lone pairs. Yes, they are not paired with anything.

does an atom have to give up or take an electron in order for it to be a radical? or if the valence shell has an odd number of electrons is it already considered a radical?

IM pretty sure whenever there is an odd number of electrons to distribute there will bw a radical, but I am not positive how to determine which element will be the radical.

If one of the electrons is unpaired it's considered a radical.

I don't think radicals are necessarily made from atoms giving up or gaining electrons. If they do that, they would make bonds. I think radicals are made because of combustion or if something breaks a bond. Some examples would be gas from a muffler or broken bonds because of UV rays.
