An electron in the excited state does not necessarily return to a ground state in a single jump.
Indicate whether the statement is true or false
Question 2
Why might the relative amount of deuterium (a heavier isotope of hydrogen) help to determine temperature?
A) Because it is heavier it would take more energy to excite and evaporate.
B) It indicates that there is more radiation because it has picked up an extra neutron.
C) It would fall out of the sky more readily when it is colder because it has a higher density.
D) It does not fragment as readily in the presence of UV and so more indicates more UV radiation.
E) none of the above
