# What is the probability function for the Hydrogen atom?

##### 1 Answer

The wave function of an electron gives the information about the electron in an atom. The wave function

The wave function

Thus, the probability of finding an electron at a given point is,

This is not only true for a hydrogen atom but, for any atom or any quantum mechanical system.

In case of hydrogen atom, however, the energy of the electron depends only on the value of the principle quantum number
