METALS
Physical Properties:
1. Solid.
2. High melting and boiling point.
3. High density.
4. Malleable and ductile.
5. Good conductor of heat and electricity.
Chemical Properties:
1. Metal + Oxygen ------> Metal oxide
1. Metal + Oxygen ------> Metal oxide
e.g., 4Na + O -------------> 2Na2O
2. Metal + Water -------> Metal
3. Metal + dil acid ---------> Salt + Hydrogen
4. Metal + Chlorine ---------> Metal Chloride
5. Metal + Hydrogen --------> Metal Hydride
2. Metal + Water -------> Metal
3. Metal + dil acid ---------> Salt + Hydrogen
4. Metal + Chlorine ---------> Metal Chloride
5. Metal + Hydrogen --------> Metal Hydride
NON-METAL
Physical Properties:
1. Solid, liquid and gas.
2. Not malleable and ductile.
3. Low melting and boiling point.
4. Poor conductor of heat and electricity.
