Chapter 7, Problem 7B.9P

(a)

Interpretation Introduction

Interpretation:

The probability of finding the electron within a small sphere of radius $1.0\text{pm}$ centered on the nucleus has to be calculated.

Concept introduction:

The wave function represents the exact position of the electron in an atom.  For a wave function to be acceptable, it must be normalized.  The wave function is represented by $\psi$ in the quantum mechanics.
