Work on your Wave WS

You have 20 minutes to review your notes and complete the WS.

Atomic Orbitalsand

their shapes!!!

s Orbitals- spherical

Each one can hold 2 electrons!

1s orbital 2s orbital

p Orbitals- the dumbbells

Each p subshell actually consists of three p orbitals of equal energy: px py pz

Each of the three p orbitals is dumbbell shaped and all are oriented perpendicular to one another.

The max. capacity of each p orbital is 2e-.

This accounts for the total capacity of the p subshell as being 6 e-’s.

Each p subshell consists of a set of three p orbitals of equal energy, px py pz

Shown together the three orbitals look like this

d Orbitals

The d subshell actually consists of a set of five d orbitals of equal energy

Each d orbital can hold a maximum of 2e- This accounts for the total capacity of the d subshell as being 10 e-’s
