What type of atoms form covalent bonds?
- Nonmetals
- Electrons are shared by both atoms
Chemical Formula for Sulfur dioxide

SO₂
Chemical Formula for Silicon Tetrachloride

SiCl₃
Chemical Formula for Dinitrogen oxide

N₂O
Chemical Formula for Tetraphosphorus hexoxide

P₃O₆
Ionic Compounds
- Formed with negative and positive ions
- (no sharing of electrons)
- Held together by Ionic bonds
- Found in Ionic Lattice
Bond Types based on electronagtivity
- Greater than 1.7=ionic bond
- 1.7-0.4=polar covalent
- Less than 0.4=Non Polar covalent
Naming Ionic Compounds
- Metal ion (cation) first-keeps elemental name
- Nonmetal (anion) second-replaces ending with ide
Name the following ionic compounds:
MgCl₂Al₂O₃NaBr
- Magnesium Chloride
- Aluminum Oxide
- Sodium Bromide
Transition Metals

Need to indicate charge of an ion because they have more than one charge state.
What do you do if more than one polyatomic ion is needed?
