Question
Classify the elements based on their property of conductivity with suitable examples.
✓

Answer

  • Elements can be classified into three categories on the basis of their conductivity:
  • $(1)$ Metallic elements :
  • They have high values of electrical conductivity.
  • For example, Copper $(Cu)$, Aluminium $(Al)$, Silver $(Ag)$.
  • $(2)$ Non-metallic elements :
  • They have low values of electrical conductivity.
  • For example, Oxygen $\left(\mathrm{O}_2\right)$, Nitrogen $\left(\mathrm{N}_2\right)$, Chlorine $\left(\mathrm{Cl}_2\right)$.
  • $(3)$ Metalloids :
  • The values of their electrical conductivity is lower than metals but higher than non-metals.
  • For example, Silicon $(Si)$, Germanium $(Ge)$.

Bharat had an electric iron. He connected it into two-pin plug. Obviously the green wire was left unconnected.
After few days, once his sister got a severe electric shock while ironing the clothes. Bharat called the electrician. He told that this situation could have been avoided if she would have connected the green wire also by using a three-pin plug. Bharat learnt a lesson.
(1) Which terminal gets connected by using a green wire?
(2) What care should Bharat take to avoid such mistakes?
(3) If you were the electrician, what else would you do apart from mere explaining to Bharat?
