    Expected value for potential energy (quantum)

    i am having trouble following the units. aren't you missing an e^2 term? the units should go: V(r) = Ze^2/(4(pi)e0) * <1/r> Ze^2 = C^2 e0 = C/(V*m) 1/r = 1/m So, V(r) = C*V = J if my <1/r> is actually (2/a), i think i substitute in the following: Z= 2 (no units for...

    Expected value for potential energy (quantum)

    I am trying to find the expected potential energy. The equation I have is: Z --------- x (1/r) = V(r) 4*(pi)*E Z is charge which equals 2 for Helium (number of protons) and I would sub in (2/a) for 1/r i am assuming i would use Bohr's radius here where...

    Expected value for potential energy (quantum)

    Homework Statement The radial distribution factor for a 1s orbital given: R10 Calculate the expected value for potential energy of a He atom in the ground state. Homework Equations i understand the integral math where I solve down to <1/r> = z/a but now, how do i use the V(r) =...

    Wavefunction and Electron Configuration (Toughy of the Day)

    Does this mean I can just use the sin'2 in angular part to assign l and m equal to 2 and then determine n from there? Even if the functions don't match exactly.

    Wavefunction and Electron Configuration

    are you saying that since the theta funtion part has sin^2 theta in it, and the only one in my table that does is theta 22, then both l and m are 2 since the function overall is a product of R(nl) and Theta(lm) Phi(m)

    Wavefunction and Electron Configuration (Toughy of the Day)

    sorry i am a pain in the butt here, but now I am even more confused... how did you simplify down to that? all of functions in my table retain a Z^(3/2) term, but none have exponential like this or sin^2 theta

    Wavefunction and Electron Configuration (Toughy of the Day)

    that is where I am confused. I see the hydrogen like wavefunction tables that contain R and (Theta Phi) values, but my function here does not fit any of them. Am I suppose to do something to the wave function first? If I am suppose to normalize then what would my boundaries be? and do I need...

    Wavefunction and Electron Configuration

    I think you are referring to the radical substitution tables that are also in my quantum book, but the equation here does correlate to the tables here, I am not sure if i need to normalize it or separate terms or what.

    Wavefunction and Electron Configuration (Toughy of the Day)

    The wave function for a particular electron is given by: Psi= 4/(9√(4π)) * (6/a)^(3/2) * (r/a)^2 * e^(2i(phi) - (2r)/a) * sin^2 (θ) a) This is an electron in which subshell? b) This is an electron in an atom of which element? c) What is the ionozation energy for this electron, assuming...
