Hey!
I'm having a bit of trouble with solving the following problems, so help would be appreciated a lot!
Consider a hydrogen atom in the ground state. Calculate the relative probability of finding the electron in the area described:
a) In a sphere of volume 1.0 E-3 pm3 centered at the nucleus
Well this wasn't really hard: the volume is 1.0 E-3 pm3 = the volume of a sphere = 4/3 pi r3.
Dividing by 4/3 pi and taking the 3-rd square root gave me r= 0.0620350491 E -12 m.
The psi2 function of the 1s orbital is:
(1/pi) (1/a0)^3 e-2r/a0
The radial probability distribution is obtained when the function above is multiplied with the formula for the surface of a sphere given by 4 pi r2. Integrating between 0 and the radius 0.0620350491 E -12 m gives a probability of 2.2E -9 .
Now the hardest part. I don't know how to get to a right answer with these questions:
Calculate the relative probability of finding the electron in the area described:
b) In a sphere of volume 1.0 E-3 pm3 centered on a point 1.0 E-11 m from the nucleus.
c) In a sphere of volume 1.0 E-3 pm3 centered on a point 53 pm from the nucleus.
