Final answer:
The shortcut (noble gas) configuration for Iodine is [Kr] 5s2 4d10 5p5, using the noble gas Krypton as the reference for the inner electrons.
Step-by-step explanation:
The shortcut (noble gas) configuration for Iodine (I) is [Kr] 5s2 4d10 5p5. This notation indicates that Iodine has the same inner electron configuration as the noble gas Krypton (Kr) up to the 4p orbital, and then continues with its own valence electron configuration in the 5s and 5p orbitals. Remember that when writing noble gas configurations, we use the symbol of the last noble gas that occurred before the element in question on the periodic table, followed by the configuration of the remaining electrons.
