The Periodic Table
Families on the Periodic table
Non- Metals- Dull, poor condutors
Metals- Shiny, good condutors of heat and energy, malleble and ductile
Alkali metals- Any metal in group 1A of the periodic table
Akaline earth metals- Any metals in group 2A on the periodic table
transition metals on of the group b elements highest s energy level is occupied

Atomic Radius vs. Atomic Number
PT:L->R Element Gets Smaller
PT:T->B Element gets Bigger
EX:
H-Smallest
Fr-Largest
Ionization Energy
Definition:
The Amount of energy needed to remove an Electron
Trend
L->R-Energy Needed Increases
T->B-Energy Needed Decreases
Electronegativity
Definition:
The Ability to attract other electrons
Trend:
Metals will have a low Electronegativity
