प्रश्न

Write three properties of metalloids.

टीपा लिहा

उत्तर

Properties of metalloids:
Metalloids are all solid at room temperature.

  1. They can form alloys with other metals
  2. Some metalloids, such as silicon and germanium, can act as electrical conductors under specific conditions, thus they are called semiconductors.
  3. Silicon for example appears lustrous, but is not malleable nor ductile (it is brittle – a characteristic of some non – metals). It is a much poorer conductor of heat and electricity than metals.
