  82. 82In the ground state of the atom the electrons are in the lowest energy level possible. When an atom absorbs energy its in the excited state which is unstable. The atom soon will emit the same amount of energy absorbed which may be seen as visible light.In the ground state of the atom the electrons are in the lowest energy level possible. When an atom absorbs energy its in the excited sta...
