Hund’s rule
A
For degenerate orbitals the lowest energy is attained when the # of e- with the same spin is maximized

25
Dmitri Mendeleev
Came to the conclusion that elements should be grouped
26
Henry Moseley
Came up with the concept of atomic #
27
What do you add as you grow across a period
E-
28
What do you add as you go down a group
Energy levels
29
List the order of increasing size for cations anions and parents
Cations parents anions
30
Isoelectronics
Have the same # of e-
| Same electron configuration
31
Ionizations energy
Minimum amount of energy it takes to remove an e-
32
What happens to ionization energy as it goes across a period
Increase
33
What happens to ionizations energy as it does down a group
Decrease
34
Electron affinity
When you add an e-
| Exothermic
35
Electronegativity
Ability of an e- to attract e-s to itself
36
What happens to electronegative as it goes down a group
Decreases
37
What happens to Electronegativity as you go across a period
Increase
38
What happens to atomic radius as you go down a group
Increase
39
What happens to atomic radius as you go across a period
Decrease
40
What happens to s and P groups when they are with transition metals
Colored because metal ions can have a +1 oxidation #
41
What color flame does Li have
Red pink
42
What color flame does Na have
Orange
43
What color flame does K have
Purple
44
How do you get absorbable into %
```
Y = absorbance
X = molarity
X*L of solution = moles
Moles / mass from periodic table
Mass / total mass * 100
```
