Significant Figures in regards to energy states
If asked to calculate the energy of electrons in n-energy levels and just given values such as n=4 and n=1, how many sig figs should be in our answer? I've noticed in the workbook that the answer generally has 3 sig figs, but other than that I have no clue how many sig figs to leave in the answer.

Integer and fractional quantum numbers should never contribute to significant figure considerations.

What if they are the only information given? For example, the question asks what is the energy released when an electron jumps down from n=4 to n=1 and the integers were the only information given; how many sig figs should our answer have?

Re: Significant Figures in regards to energy states
In that case you must use the significant figures in the values for constants (i.e., Planck's constant, Rydberg constant, particle masses, etc.) that you happen to use in the calculation.
