The maximum electrons that can be carried by the sub-shell S is 2, by P is 6, by D is 10, and the F sub-shell can carry 14. This decides the electron capacity of the shells. The K shell contains a 1s subshell hence it can carry 2 electrons, the L shell has 2s and 2p, and can carry 8 electrons. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Which of the following corresponds to the noble gas electron configuration for iodine? [Kr]4d105p6 [Kr]5s24d105p5 [Kr]5s25d105p6 [Kr]5s24d105p6 [Kr]5s25p6Give the ground-state electron configuration for Se. 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. So Na+ is the sodium cation. The sodium cation is stable. And the reason why has to do with the resulting electron configuration. So if I look at the resulting electron configuration-- let me go ahead and use yellow here-- it would be 1s2, 2s2, 2p6. And so the electron configuration for the sodium cation is the same as neon, which is a noble gas. As the energy of the 3d orbital is higher than 4s, the last two electrons in calcium get accommodated in the 4s energy level instead of 3d. It is because of this order in which the atomic orbitals are filled as stated in Afbau’s principle that the electronic configuration of calcium is 2, 8, 8, 2 neither 2, 8, 9, 1 nor 2, 8, 10. . Electron configuration [Kr] 4d 10 5s 2 5p 5: Electrons per shell : 2, 8, 18, 18, 7 2I 2 + N 2 H 4 → 4HI + N 2. Iodine is oxidized to iodate by nitric acid: The shape of the periodic table mimics the filling of the subshells with electrons. Let us start with H and He. Their electron configurations are 1 s 1 and 1 s 2, respectively; with He, the n = 1 shell is filled. These two elements make up the first row of the periodic table (Figure 9.7.2 9.7. The electronic configuration of sodium (2.8.1) shows that sodium, Na: The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in The electron configuration and orbital diagram of helium are: The n = 1 shell is completely filled in a helium atom. The next atom is the alkali metal lithium with an atomic number of 3. The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium.
