The Periodic Table
Trends
Electron Configurations
Each family shares similar properties
The number of electrons in the OUTER MOST orbital dictates 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
H Smallest
Fr Bigger
Electronegativity
Def.
The ability to attract other electrons.
Trends:
Nonmetals will have a higher electrnegativity
Metals have a low electronegativity
Ionization energy
Def.
The amount of energy needed to remove an electron.
Trend
L->R Energy increases
T->B Energy need decreases.
