A hydrogen is in the excited state of n=4. Using the Bohr theory of the atom, find the radius of the orbit.
Find the linear momentum of the electron. (kg*m/s)
Find the angular momentum of the electron. (J*s)
r = a*n^2
??? maybe L = sqrt(l(l+1)h/2*pi)
The Attempt at a Solution
I found that a for hydrogen was 5.291772*10^-11m, so I calculated that r was .84668352 nm.
After that I tried the equation for L, but it gave the wrong answer for angular momentum.
Is there any equation that can find the linear and angular momentum of the electron using the information I am given?
