Atomic Spectra & Energy levels confusion

Postby 304751905 » Fri Sep 30, 2016 4:59 pm

Hi! Today in class we learned about the equation E2= -hR/n2. I'm confused as to why the E2 is lower as the energy level n (1,2,...) gets bigger. I get that it makes the denominator get larger and larger which makes the result smaller, but conceptually I thought it would be the opposite...

And don't forget about the negative symbol (if I am understanding you correctly). Higher energy levels are of course higher in energy, thus dropping from a higher level to a lower level will release energy, resulting in a negative delta E.

Yes that is what I meant! Ok thank you!
