Which statement corresponds to emission spectra?
A.
When an electron drops from a higher energy level to a lower level, the difference of energy between the two levels corresponds to a specific color, which is a bright line.
B.
When an object with a continuous spectrum is transmitting through a cool gas of another element, the energy transitions within the atoms of the gas and produces a dark line.
C.
When an atom loses an electron, the difference of energy between the two levels corresponds to a specific color, which is a bright line.
D.
When an object with a discrete spectrum is transmitting through a hot gas of another element, the energy transitions within the atoms of the gas produce a dark line.
E.
When an atom gains an electron, the difference of energy between the two levels corresponds to a specific color, which is a bright line.
