Electron Configurations
Each family share similar properties
The Number of electrons in the

Orbital dictate properties
Examples:
group 18 - Filled and Stable
Group 1 - 1e / UNSTABLE
Atomic Radius vs. atomic number
PT: L -> R Element gets smaller
PT: T-> B Element gets Bigger
Fr- largest
H- smallest

Amount of energy needed to remove and electron
Trend:
L -> R - Energy need increases
T -> B Energy need decrease
Electronegativity
The Ability to attract other electrons

Trend:
Nonmetals will have a higher electronegativity
Metals will have a low electronegativity
