Chemistry Chapter 6: Periodic Table and Periodic Law

Shiny, smooth, good conductors

Indicates the relative ability of an atom to attract electrons.

This main group possess a wide range of chemical and physical properties

Atomic radii ________________ as you move down the groups.

The highly reactive 7A group of elements.

Ionization energy ________________ as you move left to right across periods 

Ionic radii ___________________ as you move down the groups.

Elements are classified as either:

Positive ions are ______________ than/as neutral atoms

Credited with establishing the first widely accepted method for organizing elements

Periodic law states that when elements are arranged by increasing atomic number, there is a:

Atomic radii ________________ as you move left to right across periods 

This electron level is not filled in a predictable manner.

Elements in the same group on the periodic table have the same chemical properties because 

States that atoms then to gain, lose, or shareelectrons to acquire a full valence
