Can anyone please help by directing me in some direction? Thanks! (and I understand that xepma kindly helped me out, so thank you! But I'm still lost on where to go, because I have tried the integral, but I just can't seem to get it. =.=)

All right, I tried it. =.= I came out in circles. My ending was: (1/(32pi(a^2))) * int((4-4u+(u^2))*(e^-u)) du, where u = r/a And then I got stuck. :P

Okay, I'll try it out. But just for an extra clarification, when you put exp(-y b), you substituted (-y b) (which equals -y/b?) in for r/a, correct? All right, I'm going to try it now...thanks!

Thanks! But...I'm still a bit confused. So in order to find the probability of finding the electron between the two spheres of radii, I have to differentate the integral? Doesn't that cancel it out?

Homework Statement For a hydrogen atom in a state with n=2 and l=0, calculate the probability of finding the electron between two spheres of radii r = 5.00a[SIZE="1"]0 and r = 5.01 a[SIZE="1"]0. Homework Equations As stated above, calculate the probability of finding the electron in...
