I solved a question that uses this formula, (E= RH(1/nf2 -1/ni2)
My Answer came out (-)1.2 x 10^-18 and my other answer is (-)2.3 x 10^-18
So which Emits the Most energy?
Is it the negative (-1.2E-18), or negative (-2.3E-18)?
Also, does (-3E-18) Release more energy than (-2E-18)
Or does (-2E-18) Release more energy than (-3E-18)?

You have calculated the difference of 2 energy levels in hydrogen. Your formula should be
E= RH(1/nf^2 -1/ni^2). (You should show the squaring of the n values.)
Also you need units for your answers. This will depend on the units used for RH, but is probably joules(J).

If nf
If nf>ni (e.g going from level 3 to level 4) you will get a negative answer indicating a photon has been absorbed because you have 'gone up' energy levels.
Both of your answers are negative. So neither of your answers refers to emitting energy; they both refer to absorbing energy. You might want to re-check what you have done.
To compare the actual amounts of energy (absorbed or emitted), simply ignore the signs. So (-3E-18)units is a bigger amount of energy than (-2E-18)units.
