The outermost energy shell of an atom, containing the valence electrons involved in the chemical reactions of that atom. orbital. The three-dimensional space where an electron is found 90% of the time. outermost. How an atom behaves chemically mostly depends on the number of electrons in the atom's ____________ shell.
The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.he general concept of a chemical reaction has been extended to reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.
