What is a Free Radical?

WHAT IS A FREE RADICAL?
A free radical has unpaired electrons in its outermost shells, making the element or compound extremely reactive because can easily donate or accept electrons.
⁃ Free radicals are short lived, but can cause lots of damage to DNA, cell membranes, cell organelles, etc.
⁃ Fenton reaction: When Ferris Iron (Fe2+) reacts with hydrogen peroxide, it forms forms Ferric Iron (Fe3+), Hydroxide, and Hydroxyl radical (one of the most damaging free radicals)
