Which of the following is accurate in describing the placement and classification of iodine? a. iodine is located in period 5, group 17 and is classified as a nonmetal. b. iodine is located in period 7, group 6 and is classified as a metal. c. iodine is located in period 17, group 5 and is classified as a nonmetal. d. iodine is located in period 6, group 7 and is classified as a metal.

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 =

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.

answer; ///(a) ;
