Orbitals, Atomic Energy Levels and Sublevels (Intro to Quantum Numbers) Chem 110

N equals the

Size and Energy Level

lowercase L (l) equals

the shape of the orbital

when l is 0

we get S orbital

when l is 1

we get P orbital

when l is 2

we get d orbital

when l is 3

we get f orbital

equation for l is always

$$l\le n-1$$

S corresponds to the

Sub level

When n = 1 what does l equal

l = 0 (s)

when n = 2 what does l equal

l = 0 (s)

l = 1 (p)

when n = 3 what does l equal

l = 0 (s)

l = 1 (p)

l = 2 (d)

when n = 4 what does l equal

l = 0 (s)

l = 1 (p)

l = 2 (d)

l= 3 (f)

how many sub levels is n = 4

4 Sub Levels (4s, 4p, 4d, 4f)

$m_{l}$ =

Orientation

which axis are these three along

$m_{l}$ will always vary between

-l $\le$ $m_{l}$ $\le$ l

when l = 0 (s) what does $m_{l}$ equal

$m_{l}$ = 0

when l = 1 (p) what does $m_{l}$ equal

$m_{l}$ = -1, 0, 1

when l = 2 what does $m_{l}$ equal

-2 $\le$ $m_{l}$ $\le$ 2

how many ways can an electron spin

Two

Exactly what ways can an electron spin

Clockwise and Counter-clockwise

$m_{s}$ =

electron spin

$m_{s}$ can equal

+1/2 ⬆

-1/2 ⬇

what does every electron in an atom have?

a unique set of 4 Quantum Numbers/Units

What are the 4 Quantum Numbers/Units

n , l , $m_{l}$ , $m_{s}$
