Answer 2

Answer: The correct answer is Option A.

Explanation:

Iodine is the 53rd element of the periodic table. The number of electrons present in this element are 53.

The electronic configuration of this element = $[Kr]4d^{10}5s^25p^5$

As, the electrons are filled in the orbitals having n = 5. So, it is present in Period 5.

And, the number of valence electrons of this element is 7. So, it is present in Group 17.

Hence, the correct answer is Option A.
