Question

How many inner shell electrons does an iodine atom contain?

Answer 1

electron configuration notation: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^5. noble gas notation: [Kr] 4d^10 5s^2 5p^5. contaions 46 inner shell electrons.

Answer 2

46 inner shell electrons

Step-by-step explanation:

Iodine is a chemical element that belongs to the group 17 and period 5 of the periodic table. It is p-block element that has atomic number 53.

The ground state electronic configuration of iodine is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁵.

There are 7 valence shell electrons and 46 inner shell electrons in the ground state of iodine.
