Vocabulary
The energy it takes to break a bond
Bond energy
A bond where electrons are lost or gained.
Ionic
Draw Cl2
single bond, each chlorine has 3 unshared pairs
TRUE or FALSE?
All ionically bonded compounds are polar.
TRUE! They have a + and - ion (so they have opposite charges on opposite sides)
DAILY TRIPLE!

carbon
nitrogen
oxygen
unshared pair
What type of bond forms between 2 nonmetals?
Covalent
Draw NH3
all single bonds, 1 unshared pair on nitrogen
DAILY DOUBLE!
What are 2 terms for a molecule with a positively and negatively charged sides?
Polar
Dipole
Draw NH4 +1
Tetrahedral with brackets and charge
The mixing of orbital shapes (s + p)
hybridization
A bond between a metal and a nonmetal
Ionic
Draw N2
triple bond, each nitrogen has 1 unshared pair of electrons
Term for attraction between 2 polar molecules
dipole-dipole forces
What does VSEPR stand for?
Valence Shell Electron Pair Repulsion
The ability of metals to be bent or dented without breaking
malleability
What is the simplest formula when aluminum bonds to oxygen?
Al2O3
DAILY DOUBLE!
1) Draw HCN
2) What shape does it have?
1) triple bond between C and N, single between H and C. 1 unshared pair on N.
2) linear
What attractive force allows DNA to zip and unzip?
hydrogen bonds
Term for 2 different molecules with the same formula
A molecule that gains or loses electrons
Polyatomic ion
All diatoms form this type of bond.
(ionic, polar covalent, nonpolar covalent, metallic)
Nonpolar covalent (electronegativity difference = 0)
What geometric shape does CH2O
