Single electron in a Lewis Structure

Postby Bronson Mathos 1H » Thu Nov 19, 2020 1:47 pm

Hello, I am a little lost on making Lewis structures and was wondering if it is possible to have an unpaired electron in a Lewis structure?

Hi!
It’s possible for there to be an unpaired electron in a Lewis structure. When it happens the molecule is called a radical, because one of its electrons are unpaired and it’s highly reactive. An unpaired electron in a Lewis structure happens when there is an odd number of valence electrons when you add up the electrons of all the atoms involved in the structure.

Adding onto the above poster, radicals have very short lifetimes and they damage DNA since they can react with it. That is why we need things like Vitamin C and Vitamin E which react with radicals before they cause damage.

Lavelle said that typically if you're making a Lewis Structure and count an odd amount of electrons you should be wary and double-check the charge because usually all the electrons would be paired. However, it can happen that there is an unpaired electron and when this is the case it is known as a radical.

Yes, it's possible when the number of valence electrons is an odd number. This means that the molecule is a radical and highly reactive.

Yes. If there is a single unpaired electron in a lewis structure, this is a radical as the others said.
