the principal quantum number is n. what does it do?

n tells you the amount of energy in an electron— the shell it occupies.

any positive nonzero integer!

(l)

within a shell, there are multiple values for the ANGULAR MOMENTUM quantum number. What’s that?

any number up to one less of n.

this determines what shape the electron is in.

the L subshell comes with the letters you’re familiar with! what are they?

S - 0

P - 1

D - 2

F - 3

m of l, is the magnetic quantum number. what’s that?

-1, 0, 1… it’s basically the absolute values plus zero.

it’s all the possible orientations an electron can be in. these orientations are called orbitals. each number designates for a specific orbital.

what are the shapes connected to the l number?

the angular momentum number’s shapes go as follows

• 0, s, spherical

• 1, p, dumbbell shaped

• 2, d, rosette or torus

• 3, f, whatever

Atomic radius

Increases as you go down, decreases as u move right

Ionization energy

Decreases as you go down, increases as you go across. Unless you slowly remove electrons for IE THAT TRANSCENDS SHELLS!
