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?<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Complete Electron Configuration for Iodine (I):<\/strong> Noble-Gas Notation for Iodine (I):<\/strong> Number of Inner-Shell Electrons in Iodine:<\/strong> Explanation:<\/strong><\/p>\n\n\n\n Iodine (I) has an atomic number of 53, which means a neutral iodine atom contains 53 protons and 53 electrons. To write its electron configuration, the electrons are placed into orbitals following the order of increasing energy levels using the Aufbau principle.<\/p>\n\n\n\n The complete electron configuration starts with the lowest energy orbital and fills upward:<\/p>\n\n\n\n Adding up the electrons confirms that this configuration accounts for all 53 electrons.<\/p>\n\n\n\n The noble-gas notation simplifies this by replacing the configuration of krypton (atomic number 36) with [Kr], since krypton has 36 electrons. So, starting from [Kr], the remaining 17 electrons are written as 5s\u00b2 4d\u00b9\u2070 5p\u2075.<\/p>\n\n\n\n Inner-shell electrons are those not in the outermost shell (valence shell). For iodine, the electrons in the n=5 shell (5s\u00b2 5p\u2075) are the valence electrons (7 in total). Subtracting these from the total gives the number of inner-shell electrons: These inner-shell electrons occupy the 1s through 4d orbitals and help shield the nucleus, playing a role in the chemical reactivity and bonding behavior of iodine.<\/p>\n","protected":false},"excerpt":{"rendered":" Write both the complete electron- configuration notation and the noble-gas notation for iodine, I.
