Quantum Mechanical Model Quiz

The Quantum Mechanical Model describes the motion of electrons as

• moving in waves

• moving in circular orbits

• moving in jumps

• not moving at all

Just like in the Bohr Model, energy changes for electrons in the Quantum Mechanical Model can be described as

• happening continuously

• happening gradually

• happening in specific amounts

• not happening at all

Which of the following describes an electron cloud?
