Question

In 16 group element, sulphur, selenium and tellurium are respectively :

• A. Insulator, Semiconductors and Semiconductor.
• B. Semiconductors , Insulator and Insulator.
• C. Insulator, Insulator and Semiconductor.
• D. Semiconductors, Insulator and Semiconductor.

Answer 1

The correct option is A Insulator, Semiconductors and Semiconductor.

Sulphur is non metal.It has the properties of poor conductor of both heat and electricity.It is weak,dull and can be easily breakable.

As we move from top to bottom in group the conductivity of elements increases so the sulfur, selenium and tellurium are Insulator, Semiconductors and Semiconductors respectively.

Hence option A is correct.
