Final answer:
The condensed electron configuration of iodine is B) 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵.
Step-by-step explanation:
The condensed electron configuration of iodine is B) 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵.
In the electron configuration, each number and letter represents a specific sublevel and orbital in an atom. The numbers before the 's', 'p', and 'd' orbitals indicate the energy level, while the superscripts indicate the number of electrons in each orbital. For example, 1s² means that there are 2 electrons in the 1s orbital.
In the case of iodine, the electron configuration starts with the noble gas configuration of [Kr] (representing the completed 5s² 4d¹⁰ sublevels of krypton), and then adds the remaining electrons in the order of increasing energy levels and orbitals up to the 5p sublevel.
