Free Radicals

Presentations | English

Radical, also called Free Radical, in chemistry, is a molecule that contains at least one unpaired electron. Most molecules contain even numbers of electrons and the covalent chemical bonds holding the atoms together within a molecule normally consist of pairs of electrons jointly shared by the atoms linked by the bond. Free radicals are oxygen-containing molecules with an uneven number of electrons. The uneven number allows them to easily react with other molecules. These atoms can cause large chain chemical reactions in your body because they react so easily with other molecules. These reactions are called oxidation. Atoms are surrounded by electrons that orbit the atom in layers called shells. Each shell needs to be filled by a set number of electrons. When oxygen molecules split into single atoms that have unpaired electrons, they become unstable free radicals that seek other atoms or molecules to bond to.
