Of the elements Fe, Hg, U, and Te, which is a representative element?

a. U

b. Te

c. Fe

d. Hg

Answer: Option (b) is the correct answer.

Explanation:

Elements which are placed from group 13 to group 18 are known as representative elements.

For example, tellurium is a group 16 element and hence, it comes under representative elements.

On the other hand, both Fe (iron) and Hg (mercury) are transition elements. Hence, they are d-block elements and not p-block elements.

Uranium (U) is an actinoid element and hence, it is a f-block element.

Thus, we can conclude that out of the given options Te is a representative element.
