1. Ionic Bond Review Electron is taken by one atom from another atom.
Bond is formed by + and – charges
Metal + nonmetal

2. Ionic Bond Review
The two atoms can only combine in one way in ionic bonds, so the naming is simple
NaCl – sodium chloride
KBr – potassium bromide
CaF2 – calcium fluoride

3. Covalent Bond Review Electrons are shared between two atoms
Bond is formed by a shared pair of electrons
Generally a nonmetal + nonmetal

4. Covalent Compound Naming
Uses a different system than ionic because nonmetals form a variety of combinations NO
NO2

5. Covalent Compound Naming
One similarity
First element still keeps the same name; the second element ends in -ide

6. Covalent Compound Naming
Differences
Both compounds get a prefix that tells what the number of atoms of each element has.
ONLY EXCEPTION: If the first element has only one atom, the prefix mono- is dropped

7. Prefixes One = Mono- Two = Di- Three = Tri- Four = Tetra-
Five = Penta-
Six = Hexa-
Seven = Hepta-
Eight = Octa-
Nine = Nona-
Ten = Deca-

8. Given name Diphosphous monoxide Trisilicon tetrasulfide
Carbon tetrachloride

9. Given Formula
P2O3 CO
