Sue Blakely. 1 Ch 1: Introduction to Radicals The idea of a substituted carbon atom with 7 valence electrons being a reactive intermediate was established and accepted in around the 1930’s. The two most f The ocean/layer of gas that surrounds the Earth. It is composed of 78% Nitrogen and 21% Oxygen. The other 1 % is a mixture of other gasses. We depend on this balance of gas for our survival. When it is out of balance, we have problems.. and the Impact on Living Things. Earth’s Atmosphere.
