Question

why the n2 in rybderg formula cannot be negative​.

Answer 1

Since you are dealing with fractions this means the lowest n-value will be the larger number. ... Therefore, as you increase the value of n you are getting closer to the positive side of the number line, which means your energy is getting larger. To summarise, because the Rydberg formula is a binding energy it is negative
