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 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.n a substitution reaction, a functional group in a particular chemical compound is replaced by another group. These reactions can be distinguished by the type of substituting species into a nucleophilic, electrophilic or radical substitution.
