Chem 130 Chapter 8

Front 1

Atomic size (horizontally)

Back 1

Decreases as more protons are added but no new shells are made

Front 2

Atomic Radius (vertically)

Back 2

Increases as the shells get farther away from the nucleus and its protons.

Front 3

ionization energy (vertically)

Back 3

decreases as you go down as electrons are easier to remove the further they are from the nucleus

Front 4

ionization energy (horizontally)

Back 4

increases to the right as elements are more stable towards that direction as the shells fill but after a full orbital the IE drops a bit then rises

Front 5

Paramagnetic

Back 5

Has unpaired electrons and is attracted to a magnetic field

Front 6

Diamagnetic

Back 6

All electrons are paired and is not attracted to a magnetic field

Front 7

Valence electron configuration

Back 7

Just the electrons in the last period or the part after the pseudo - noble configuration

Front 8

Noble gas configuration

Back 8

Add the last noble gas in brackets and put in the valence electrons

Front 9

n

Back 9

principal quantum number. the level of the shell

Front 10

l

Back 10

angular momentum quantum number. the type of orbital

Front 11

ml

Back 11

magnetic quantum number. the shape of the orbital

Front 12

ms

Back 12

spin quantum number. direction of the electron spinning. 1/2 or -1/2
