... You can recognize an excited state electron configuration. If the configuration does not match that on the Periodic Table for that number of electrons, then it is an excited state. 9. When an electron returns from a higher energy state to a lower energy state, it emits a specific amount of energy ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
