Electrons have wave-particle duality. Why?

• They are particles with mass. They move so fast in electron clouds that they behave like energy.

• They are particles, but have no mass. They move so fast in electron clouds that they behave like energy.

• They are pure energy, but have no mass. They are compact like particles and similar behaviors to particles.

• They are pure energy and have mass. They are compact like particles and similar behaviors to particles.
