Wave mechanical model |
The atom is a (+) nucleus surrounded by a cloud of (-) charges. The densest portion of the cloud is most probable location of an é. Electrons are probably in orbitals W/in the PELs there are sublevels, and orbitals w/in the sublevels
When... n=1 has only 1 sublevel= ‘s’ can have only 1 orbital= max of 2é n=2 2 sublevels= p=3 orbitals=2x3=6é 2+6=8é n=3 3 sublevels= s=1 orbital= 2é — p=3 orbitals= 6é | 18é d=5 orbitals= 10é —
n=4 4 sublevels= s=1 orbital= 2é — p=3 orbitals= 6é | d=5 orbitals= 10é | 32é f=7 orbitals= 14é — |

Aufbau |
Lowest energy shells are occupied first before moving on (Ex- 1s will be occupied first before 2s) |
|
|
Paulis exclusion |
No 2 electrons occupying the same orbital, have the spin __⬆️⬇️__ __⬆️⬆️__ __⬇️⬇️__ orbital ✔️ ❌ ❌ |
|
|
Hundi rule |
Always single occupancy of the orbital first before pairing. (ex: 7éN- 1s^2, 2s^2, 2p^3) __⬆️__ __⬆️__ __⬆️__ ✔️ 2p __⬆️⬇️__ __⬆️__ __blank__ ❌
