Unit 5: Ionic Bonding & Intramolecular Forces

Ion

When an electron is gained or lost. (Cation or Anion)

Metals..

GIVE away their ve.

Nonmetals..

TAKE ve.

Cation

Positively charged ions, elements on the left side LOSE electrons.

Anion

Negatively charged ions, elements on the left side GAIN electrons.

Ion Symbol

Exponent to the right and above ion’s chemical symbol.

Ionic Bonding

When cations (metals) are attracted to anions (nonmetals).

Intramolecular Forces

The forces that cause attraction between atoms or ions. Ionic, covalent, and metallic are examples of intramolecular forces.

Ionic vs Covalent

Box the first element, and label whether it is a metal or nonmetal.

Ionic Bonds

Metal + Nonmetal.

Ionic Lewis Dots

Draw LDD or two atoms separately (BEFORE, DURING, AFTER)

Octet Rule

Each atom wants 8 ve to be stable.
