|
Aufbau principle |
Electrons fill the sub shells with the lowest amount of electricity |
|
|
Hund Principle |
In a sublevel, before any orbital has 2 electrons, every orbital in the sub level must have 1 electron |
|
|
Pauli |
Electrons need to be moving in different directions with half integer spins “S” quantum number |
|
|
Quantum jump |
An abrupt transition of energy states like with the crummy rule(I think) |
|
|
How many orbitals |
N^2 |
|
|
How many electrons |
2n^2 |
|
|
What is N in an electron configuration and what can be found from it |
It is the number in front of the symbol for the element and you can find the number of orbitals and electrons |
|
|

|
What are the equations for AM- atomic mass |
1. AM=(mass)(abundance)+(mass)(abundance) 2. AM=(x)(mass1)+(1-x)(mass2) Note: always make percentage divided by 100 when inputting for equation |
|
|
1,3,5,7 are all the amount of columns in each section divided by two. Why? |
There are two electrons per box |
|
|
Planetary model. Who made it? |
Bohr |
|
|
Heisenberg uncertainty |
We cannot know both the position and speed of a particle like electrons |
|
|
Crummy rule |
Columns of chromium and copper are pushed one electron more and the s block is pushed one back to maintain an even amount of electrons, this Chang rid called a quantum jump |
|
|
L quantum number represents what |
Shape of orbital and sublevel |
|
|
Which quantum number is always greater than L |

|
|
Pauli principle |
No two electrons in an atom can have the same 4 quantum numbers: N L M S |
|
|
Mass Number |
Sum of protons and neutrons |
|
|

|
|
Schrödinger model |
Electrons floating in cloud |
|
|
