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
