Elements Iodine (I) Iodine (I) Iodine is a chemical element of the periodic table with chemical symbol I and atomic number 53 with an atomic weight of 126.904 u and is classed as nonmetal and is part of group 17 (fluorine group). Iodine is solid at room temperature. Tellurium Periodic table Xenon Iodine in the periodic table 2.2 Electron Configuration [Kr]5s 2 4d 10 5p 5. The maximum allowable concentration of iodine in air should not exceed 1 mg/m 3 (8-hour time-weighted average The electron configuration of Ni 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 8 as the atom loses two electrons from the 4s subshell. What is the importance of knowing the electron configuration of Nickel? Knowing the electron configuration of Nickel is significant because it accounts for the chemical and physical properties of Nickel atoms. Iodine has an atomic number of 53. This means that it has a total of 53 electrons. The noble gas closest to it is krypton, with an atomic number of 36. Therefore, there are only 17 remaining electrons. Hence, the electron configuration of iodine can be written as [Kr] 4 d 10 \text{[Kr] }4\text{d}^{10} [Kr] 4 d 10 5 s 2 5p 5 5\text{s}^2\text{5p n = 5 shell: 50 n = 2 shell: 8 n = 2, l = 0 subshell: 2 n = 2, l = 1 subshell: 6 3d subshell: 10 2s subshell: 2 5f subshell: 14 Use the periodic table to answer the questions below. Which diagram shows the correct electron configuration for nitrogen (N)? a.mc001-1.jpg b.mc001-2.jpg c.mc001-3.jpg Write the unabbreviated electron configurations of the following elements: 1) copper 1s22s22p63s23p64s23d9 2) iodine 1s22s22p63s23p64s23d104p65s24d105p5 3) potassium During the formation of a bond, the last shell of iodine receives an electron and turns into an iodide ion(I –). In this case, the iodide ion carries a negative charge. I + e – → I – Here, the electron configuration of iodide ion(I –) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 6. 53 I (Iodine) Flashcard of Iodine. Iodine is a non-metallic, dark-gray or bluish-black, lustrous solid element. It forms compounds with many elements, but least reactive than the other halogens. Iodine sublime (change directly into vapour when heated) easily on heating to give a purple colour. Iodine dissolves readily in some solvent, such as 2024-01-06. Description. Iodine is a naturally occurring element found in sea water and in certain rocks and sediments. There are non radioactive and radioactive forms of iodine. Iodine is used as a disinfectant for cleaning surfaces and storage containers and is used in skin soaps and bandages, and for purifying water. x3TWIL.
