Give the electron configuration of iodine. In the formation of an ion, what is the expected behavior of an atom with the following electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 a) gain 1 electron b) lose 1 electron c) lose 2 electrons d) gain 2 electrons e) no correct response; Write the electron configuration of Ni. 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. Iodine would have a standard electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^5 The noble gas in the row above iodine is krypton. We can replace 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 with the symbol [Kr] and rewrite the noble gas configuration of iodine as [Kr] 5s^2 4d^10 5p^5 I hope this was helpful. This video shows you how to write the ground state electron configuration using noble gas notation (abbreviation) for the elements fluorine, sulfur and cadmium. This is the shortcut or shorthand method of writing the electron configuration for elements. Only one more electron is required to attain the electron configuration of a noble gas. A sole iodine atom has only seven electrons in its outermost shell, an ionic counterpart of this atom 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. Identify elements with similar chemical properties. Google Classroom. An element A − with electronic configuration 2, 8, 8, 2 − reacts with water to form a base, which is used in the manufacture of antacids.
