- 1. Multiple ChoiceWhat does it mean to say electrons have a "dual nature"?It means they act only like a particle.They have both a wave and particulate nature.It means they have only act light light waves.They behave like Newton predicted in his laws of motion.
- 2. Multiple ChoiceWhy do electrons behave differently than protons and neutrons?All three behave the same way.There is no way to know.Electrons have a much smaller mass (1/2000) than protons and neutrons.Because of their charges.
- 3. Multiple ChoiceWhat shape are P Orbitals?Cloverleaf shapedSpherical shapedHybrid structureDumbell shaped
- 4. Multiple ChoiceWhat shape are S orbitals?Dumbell shapedCloverleaf shapedSpherically shapedHybrid structure
- 5. Multiple ChoiceWhat shape are D Orbitals?Hybrid structureSpherically shapedDumbell shapedCloverleaf shaped
- 6. Multiple ChoiceThere are 4 different types of sublevels: s,p,d,ftruefalse
- 7. Multiple Choice
How many orbitals are there in the "d" sublevel?1357 - 8. Multiple ChoiceHow many orbitals are there in a "p" sublevel?2143
- 9. Multiple ChoiceHow many electrons can the d sublevel hold?81024
- 10. Multiple ChoiceHow many total electrons can the orbitals in the "f" sublevel hold?214610
- 11. Multiple ChoiceWhich orbital has the least amount of energy?p orbitald orbitals orbitalWhat is an orbital?
- 12. Multiple ChoiceAn area of high probability of finding an electron (90% of the time) is called a(n)nucleussublevelorbitalenergy level
- 13. Multiple ChoiceThe Quantum Mechanical Model is the most recent/modern atomic model.TrueFalse
- 14. Multiple ChoiceHow many quantum numbers are there in the Quantum Mechanical Model?3246
- 15. Multiple ChoiceThe quantum number "n" represents:spinorbital orientationsublevel (shape)energy level
- 16. Multiple ChoiceThe quantum number "l" represents:spinorbital orientationsublevel (shape)energy level
- 17. Multiple ChoiceThe quantum number ml represents:spinorbital orientationsublevel (shape)energy level
- 18. Multiple ChoiceThe quantum number ms represents:spinorbital orientationsublevel (shape)energy level
- 19. Multiple ChoiceWhich scientist developed the Uncertainty Principle:E. SchrodingerW. HeisenbergI'm not certain ;-)N. Bohr
- 20. Multiple ChoiceThe Heisenberg Uncertainty Principle states:You cannot measure the momentum and exact position of an electron at the same timeelectrons occupy the orbitals of lowest energy firstan atomic orbital may describe at most 2 electronsNo two electrons can have the same set of quantum numbers
