Write both the complete electron- configuration notation and the noble-gas notation for iodine, I. How many inner-shell electrons does an iodine atom contain?

Iodine has an atomic number of 53

Electronic configuration - 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2  4d^10 5p^5

Noble gas configuration - [kr]4d^10 5s^2 5p^5

Iodine have 7 valence shell electron and 46 inner shell electron in the ground state.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck
