Probability of an electron's position (Quantum Mechanics)

Click For Summary
SUMMARY

The discussion focuses on calculating the probability of finding an electron within 10^-14m of the nucleus of a hydrogen atom in its ground state. The relevant equation involves integrating the probability density function, specifically ∫x^2 e^(-x/a) dx, ensuring normalization across the entire space. Participants emphasize the importance of integrating over angles and maintaining the normalization condition to achieve accurate results. The calculations yield insights into quantum mechanics and the behavior of electrons in atomic structures.

Homework Statement



If a Hydrogen atom is in it's ground state - calculate the probability that the electron will be found within 10^-14m of the nucleus. The nucleus can be assumed to be point like.


Homework Equations



∫〖x^2 e^(-x/a) dx〗=-e^(-x/a) [ax^2+2a^2 x+2a^3 ]+constant

Take the ground state - you should have the formula. Make sure it is normalized (when integrated over r form 0 to infinity should give 1, do not forget integrating over the angles). Calculate the integral of the probability density from 0 to 10^-14m (do not forget about the angles).
