Year 10 Chemistry RA 2
Metal + Oxygen Metal oxide
Metal + Water Metal hydroxide + hydrogen
Metal + Acid Salt + hydrogen
Reactivity- elements react when they gain / loss electrons
- outer electrons can be easily gain / lost
- more reactive – gain / loss electrons more easily
Non- metals- gain e-
- negative ion
Metals- lose e-
-
positive ion
Metal reactivity series: Potassium
Sodium Group 1
Lithium
Calcium
Group 2
Magnesium
Aluminum Group 3
Zinc
Iron
Copper Group 4
Silver
Gold
Oxidation- electron loss
- oxygen gain
Reduction- electron gain
- oxygen loss
More reactive metal – displace other metals more easily
