Unit 5 Reactions

Single Displacement Reactions

Cation Reactions: AX + B ---->BX +A

1 cation (+ion) replaces another 1 anion (-ion) replaces another

Steps: 1. Does element replace metal in compound? 2. If so, what ions are now paired? 3. Criss-Cross

Synthesis Reaction

Combustion Reaction: Complete V. Incomplete

Transition Metal has multiple charges so they multiple products

Diatomic Molecules: Pure elements that aren't just their own symbol

Element + Element -----> Compound Metal + Non Metal -----> Ionic Compound

Use of Oxidation Numbers

Should Knows:

Should Dos:

Metals lose electrons Non-metals gain electrons

Group | Oxidation# 1 | +1 2 | +2 3 | +3 4 | +/- 4 5 | -3 6 | -2 7 | -1 8 | 0
