What is an orbital?

• Certain patterns of movement for electrons

• A wedding ring

• DONUT

^{How many valence electrons does it have}

• I have no idea

• 6

• 4

• 1

True or False: Electron configuration stops at 7s.

• True

• False

How many valence electrons does carbon have: 1s²2s²2p²

• 2

• 7

• 6

• 3

What does the Pauli Exclusion Principle state?

• That you should exclude people named Pauli from your group project

• Certain particles cannot be in the same place at the same time

• Something that is used to find the ground state of an atom.

What does the Aufbau principle state?

• That in the ground level of an atom has electrons of the lowest energy level.

• That in the ground level of an atom has electrons of the highest energy level.

• That atoms needs batteries

What is Hund's rule?

• I don't know

• Every orbital in a subshell can only have 4 electrons.

• Every orbital in a subshell is singly occupied before it is doubly occupied.

• Certain particles cannot be in the same place at the same time
