Understanding Electron Wave-Particle Duality

What characteristic of electrons supports their particle-like behavior?

• They emit light.

• They are invisible.

• They can pass through walls.

• They have a definite mass and charge.

What pattern is observed when electrons pass through two closely spaced slits?

• A random distribution.

• Two distinct spots.

• A single bright spot.

• An interference pattern.

What does the interference pattern in the double-slit experiment suggest about electrons?

• They exhibit wave-particle duality.

• They are only waves.

• They do not exist.

• They are only particles.

How does the wave behavior of electrons explain their quantized energy levels?

• It makes them unstable.

• It allows them to move freely.

• It causes them to emit radiation.

• It limits them to discrete energy values.

Why don't electrons spiral into the nucleus according to wave behavior?

• Their wave nature prevents it.

• They are too heavy.

• They are not attracted to the nucleus.

• They are repelled by the nucleus.
