Using quantum theories to study the hydrogen atom allows the prediction and experimental verification of many data about atoms such as He⁺ and Li²⁺.Some quantities that can successfully be predicted about He⁺ and Li²⁺ in this manner are: A)the color of the light they will emit. B)their mass. C)their abundance in nature. D)All of the above.

The use of quantum theories allows the prediction of the energy states of atoms and the transitions between them. As different energy states correspond to different frequencies (and hence colors) of emitted light, quantum theories can be used to predict the color of light emitted by He⁺ and Li²⁺. The mass and abundance of atoms are not determined by quantum theories but are instead properties of the specific element.
