A brief review of the types of chemical bonds and their properties. Discussed properties, naming conventions, and physical properties. Easy to follow and use for help with Chemistry.

1. BONDS Metallic Non-polar Covalent Polar Covalent Ionic
Description "sea" of electrons Sharing electrons equally Share electrons unequally
Steal (Transfer) the electrons, opposite ions
attract
Memory Aid
Church dance (everyone
around the edge)
Sister's tea party (sharing the
electrons nicely)
Bully (one atom hogs the electrons
towards it) Basketball player good at stealing the ball
Sides of the periodic Table Middle Both on the non-metals side (left)
Both on the non-metals side (left)
but further apart
On opposite sides of the periodic table
(non-metals and metals)
Properties Conducts electricity Super weak bond, LOW boiling point Stronger bond, higher boiling point Very strong Bond, highest boiling point
Difference in electronegativity N/A 0-0.4 0.41-1.99 > 2.00
Example Cu (Copper) O2 H20 NaCl (Salt)
Naming Conventions Metal's name You use the di, tri, etc. You use the di, tri, etc. Just use the element names
Put the element with the lower negativity
first
Single, Double and Triple Bond Strength
Single - 2 electrons - dating Weak
Double - 4 electrons - engaged Stronger
Triple - 6 electrons - married Strongest
Octet Rule - I want 8!!!
Exceptions to the Octet Rule
Boron and Sulfur
Cation Positive
"Do you have a cat?" "Are you
positive?"
Anion Negative
