• Every electron is described by a wave function. The probability of finding an electron at a given point is Ψ2 but

Schödinger Equation Section 2.2

Math English

1. The wave function must be single valued.

2. The wave function and its first derivatives must be continuous. 3. The wave function must approach 0 as r approaches infinity

4. Integrating ΨAΨA* over all space must equal 1.

5. Integrating ΨAΨB* over all space must equal 0.
