Odd moleculeOdd molecule is a term invented by Gilbert N. Lewis in 1916 for a molecule containing an odd number of electrons. Additional recommended knowledgeTaking the p-shell elements, such molecules are rare; they are usually colored and paramagnetic, that is, attracted by a magnet. Odd molecules are 'radicals.' A fine example is nitric oxide, q.v.; nitrogen dioxide is another; chlorine dioxide is also an example, being a reddish-yellow gas. They are all fairly reactive. When including d-shell elements, i.e., the transition metals, the concept mostly doesn't apply, and this 'odd' state is not so unusual. References
