LT#5: Drawing Compounds Including Predicting Bond Types Flashcards
Define Ionic Bond
Strong attraction causing total electron transfer creating ions with full charges. EN difference of 1.7 or higher.
Electrons shared in a bond are called…
Bonding pairs
Describe Ionic Compounds
Metals and non-metals transfer electrons to create stable ions.
Because of their opposite charges, the ions attract each other forming an ionic bond.
Define Polar Covalent Bond
Unequal sharing of electrons between 2 atoms creating partial charges.
EN difference of 0.5 to 1.7
How do you draw a Lewis Diagram of an Molecular Compound?
Make sure to use the clock method when placing electrons around atoms so that you get the molecule’s correct shape.
Use circles to show electron pairs being shared. These can also be represented by sticks.
Polar bonds get partial (slight) charges.
Define Non-polar Covalent Bond
Relatively equal sharing of electrons between 2 atoms (no charges).
EN difference of 0 to 0.5
How do you draw a Lewis Diagram of an Ionic Compound?
Use arrows to show electrons transferring and show full charges on each ion.
Add enough atoms until everything is stable.
Describe Molecular Compounds
Two or more non-metals share electrons to become stable creating covalent bonds.
Pairs of electrons not shared in a bond are called…
Non-bonding or Lone pairs
