Question
Differentiate between: Metals and Nonmetals.
✓
Answer
Metals:
- Metals have a lustre.
- They are generally good conductors of heat and electricity.
- They are generally solids at room temperature.
Exception: Mercury and gallium are liquids. - Metals form basic oxides.
Nonmetals:
- Nonmetals have no lustre.
Exception: Iodine and Diamond. - They are bad conductors of heat and electricity.
Exception: Graphite. - They are generally gases and solids at room temperature.
Exception: Bromine is a liquid. - Nonmetals form acidic or neutral oxides.

Consider the following elements:
Ca, Cl, Na, I, Li, Ba, Sr, K, Br.
Separate these elements into three groups (families) of similar properties. State one property in each case on the basis of which you have made your choice.
