Question

Energy levels for an electron in a hydrogen atom are:
A. Evenly spaced
B. Farther apart near the nucleus
C. Closer together near the nucleus
D. Arrnaged randomly

Please explain.

Answer 1

b is correct

Answer 2

But why is so? @gurvinder

Answer 3

energy of nth level is -13.6/(n^2).....calculate difference b/n two adjacent levels...u shudnt have a prob now

Answer 4

\[E=Rhc*1/n^2 \]
R, h and c are constant so you can write it as E = 13,6/n^2 but than E is in eV not Joule.
n is a natural number (1;2;3;4;5...)
If you calculate some energy-levels then you quickly see that the difference in energy gets smaller and smaller for bigger n.
