Answer:
46 inner shell electrons
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.
