Overview of the Periodic Trends• Atomic Radius (AR)

- Definition: size of the atom

• Ionization Energy (IE)

- Definition: how much energy it takes to remove an e- from an atom

• Electronegativity (EN)

- Definition: atom’s attraction/pull on e-

Periodic Table Families: Key Points• The Periodic Table is split up into two main

categories: Metals & Nonmetals• Characteristics of Metals:

• Characteristics of Nonmetals:

*Elements in the same family have similar chemical characteristics

Nonmetals

Periodic Table Families• Metal Groups:

Group 1 – Alkali MetalsGroup 2 – Alkaline Earth MetalsGroup 3 – Transition Metals

• Nonmetals Groups:

Group 7 – Halogens

Group 8 – Noble Gases
