Practice question · Multiple choice
An orbital is defined as a probability distribution rather than a classical trajectory. What follows from this distinction when interpreting the two lobes of a single orbital?
Hints
- What does the wavefunction describe as a whole?
- Does a probability distribution require physical motion across its domain?
Show the answer
B. They represent one continuous probability region rather than two destinations
Why
Treating lobes as separate destinations resurrects classical trajectories. A wavefunction describes an indivisible, static probability cloud; finding an electron at one coordinate never implies physical transit from another.
