n1 and n2

Postby 705340227 » Sun Oct 25, 2020 4:25 pm

In the equation v=R[1/n1^2-1/n2^2], is n1 or n2 the shell that the electron originally starts at before it moves down the shells?

N1 is basically the final energy level and N2 is the initial energy level. During a UA session, they even suggested writing nf and ni instead so that its less confusing. Hope this helped!

For that equation, n2 should be the shell that the electron originally starts at. It's easier to think of it as n(final) - n(initial).

n1 is nFinal and n2 is nInitial, which is an easier way of looking at it. Also, for this equation, you have to always make sure the smaller n-value (bigger number overall) is in front, or else it does not work. I have no idea why, but you can always default to the other equation Lavelle gave us if this one doesn't work, lol

N2 would be the shell that the electron starts from. It might be more helpful to think of the equation as than just as n1 and n2.

For this equation, I like to think of it as v=R(1/nfinal^2 - 1/ninitial^2), meaning the final n-value(the smaller one) comes first in the equation and conversely the initial larger n-value comes second in the equation. Keep in mind that the resulting fraction inside the parenthesis(the number multiplied by R) should be positive. If the fraction is negative then the order of the n-values in the equation is wrong and will lead to an incorrect answer. Hope this helps

n1 is usually the final energy level and n2 is the initial energy level. But rather than thinking of it as 1 minus 2, also remember that it is final energy level minus initial energy level.

I would prefer you think about it as initial energy level and final energy level rather than just mathematically as light operates at discrete energy levels. It is basically n(final)- n(initial) and n2 should be the initial shell where it begins and n1 where it ends up.

Not sure if this has already been covered, but is the Rydberg equation only used when an electron moves down energy levels? Or when an electron moves to higher energy levels as well?

It will be easier to remind yourself that it should be final minus the initial.

N2 ia the final while N1 is the initial

The n1 refers to the final energy level and n2 is the initial energy level.

N1 is the final and N2 is the initial energy level of the electron. I find this very confusing so I would suggest memorizing the equation using nf and ni to denote final and initial positions of the electron :)

In this case, n=1 would be the final energy and n=2 would be the initial energy level. In order for it to be less confusing, you can replace n1 and n2 with nfinal and ninitial

How can we split this equation, if that is even possible?

Yeah so n1 is final and n2 is initial. A better way to remember it for me is the overall energy is derived from the equation change in E=E(final)-E(intial). Therefore the n1 comes from the final and by the way dont use the ryberg equation makes it harder on yourself.
