s and p orbitals are tested, d and f are not

each ‘shell’ is actually made up of subshells

first shell:

1s subshell → 1s orbital (1x) → 2e

second shell:

2s subshell → 2s orbital (1x) → 2e

2p subshell → 2p orbitals (3x) → 6e

• What are orbitals of the same energy level known as?

Assuming principal quantum number (number of shells) is n, number of orbitals in each principal quantum is n^2, and maximum number of electrons in each principal quantum shell is 2(n^2)

describe the size of the orbitals when talking about principal quantum shell (e.g 2s is bigger than 1s, 3s is bigger than 2s, therefore the number that comes before the orbital indicates the relative size

must indicate axis during drawing of principal quantum shell, even for s

• What is the Aufbau principle?
• What is the Pauli exclusion principle?
• What is the Hund’s rule?
• Relative and exact charge of the 3 main subatomic particles
• definition of isoelectronic, isotonic, isotopic
• rules of deflection

not tested: protons, neutrons and electrons all fall under baryons which are a form of fermion (Fermi-Dirac statistics) therefore they have half-integer spins (+1/2 or -1/2)

• shape of orbitals
• calculate the relative atomic mass of an atom given its percentage abundance.
