Solution
Comparing the Properties of Metalloids with those of Metals:
- State-
- Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature.
- Metalloids are generally solids at room temperature
- Lustre-
- Metals have the quality of reflecting light from its surface and can be polished. Example Gold, Silver and Copper.
- They have metallic lustre and look like metals, but many show characteristic properties of weak non-metals.
- Conductivity-
- Metals are good conductors of heat and electricity.
- Metalloids are semi-conductors of electricity and show average transmission of heat.
- Malleability and ductile –
- Metals have the ability to withstand hammering and can be made into thin sheets known as foils.
- They are generally malleable and ductile. Silicon is not malleable or ductile, but and ductility is lustrous and acts as an electrical conductor under specific conditions.
