The p sublevel has:

• 1 orbital and 2 electrons

• 3 orbitals and 6 electrons

• 5 orbitals and 10 electrons

• 7 orbitals and 14 electrons

Describe what happens when an electron absorbs energy (use the terms ground state and excited state).

• The electron gets excited and jumps on the ground.

• The electron gets too excited and gets grounded by it's parents.

• The electron jumps up an energy level to the excited state, before releasing the energy and returning to the ground state.

• The electron jumps up to the ground state, before returning to the excited state.

What are the three rules we follow for Electron Configuration?

• 1) Say please

  2) Say thank you

  3) Be polite

• 1) Orbital Notation

  2) Electron Configuration

  3) Nuclear Equations

• 1) Alpha Particle

  2) Beta Particle

  3) Positron

• 1) Aufbua Principle

  2) Pauli's Exclusion Principle

  3) Hund's Rule

Describe what happens as an electron moves from the excited state to the ground state (use the term emit).

• The electron emits the energy in the form of light.

• The electron emits an alpha particle.

• The electron emits the energy in the form of a sound wave.

• The electron emits radiation.

Describe Hund's Rule.

• Electrons will fill the lowest energy level first.

• Electrons will only pair up if they have opposite spins.

• Electrons will only pair up when they are forced.

• Electrons, as a rule, refuse to make donations to either political party.

The time it takes for half of the atoms in a radioactive isotope to decay.

• Chain Reaction

What is the difference between orbits (Bohr Model) and orbitals (Quantum Mechanical Model)?

• Orbits are fixed paths. Orbitals are areas of probability.

• Orbits are areas of probability. Orbitals are fixed paths.

• Orbit is a brand of gum. Orbitals are bones in your face.

• Orbits are individual lego pieces. Orbitals are finished lego structures.
