How to calculate a derivative like d/d(1/x)?
I do NOT mean d/dx(1/x), but really d/d(1/x). For example: The Gibbs-Helmholtz equation: http://pubs.rsc.org/services/images/RSCpubs.ePlatf...

3 AnswersPhysics7 years agoCalculating the energy of a hydrogen atom (-13.6 eV)?
The electronic energy for a one-electron system can be written as E= - (me^4)/(2 h-bar^2) (1/n^2).
For some reason, i cannot find the right answer which is -13.6 eV.
Used numbers:
e=1.602*10^-19 C
m=9.11*10^-31 kg
h-bar=6.582*10^-16 Ev*s
Should i use other numbers of units or something? 10 points for the correct answer!
2 AnswersPhysics7 years agoWhat is the reason that electronic wave functions must be antisymmetric?
The electronic wave function must be antisymmetric when two electrons are permuted. What is the reason for this? I know it has to do something with the Pauli principle, but do not really understand how the antisymmetry principle is connected to Pauli. Thank you!
