Question

How can an electron have a node?

Answer 1

Well, an electron has wave-like properties.......

Explanation:

And a node is a point on a wave-function of MINIMUM displacement.

The nodes on the given wave-function (a sine wave), `psi`, are at `0^@`, `180^@`, and `360^@` etc. The physical significance of the wave-function of an electron is that its square, `psi^2="the probability of finding the particle"`. (You will have to read your text for the Born approximation! And that's Max Born not Jason Bourne).
