Atomic Number

• number of electrons in an atom

• number of protons in an atom

• number of neutrons in an atom

• number of orbitals

Mass Number

• Number of protons in an orbital

• The amount of protons+electrons in an atom

• The amount of protons+neutrons in an atom

• the amount of electrons+neutrons

Define: Directly Proportional

• when one goes to the right the other goes to the left.

• when one goes down the other goes up

• when one goes to the left the other goes to the right

• when one goes up the other goes down

Define: Inversely Proportional

• when one goes to the right the other goes to the left

• when one goes down the other goes up

• when one goes up the other goes down

• when one goes to the left the other goes to the right

Aufbau Principle

• electrons fill lower value orbitals first (n+l rule)

• electrons fill higher value orbitals first (n+l rule)

• Protons fill lower value orbitals first (n+l rule)

• Protons fill higher value orbitals first (n+l rule)
