For example, chlorine (atomic no 17) can accept one electron to form Cl –. I don’t understand what … Since the p sub level should have 6 electrons to obtain the Argon noble gas electron configuration, chlorine has the ability to attract an electron. Lv 7. Want to see this answer and more? Therefore, elements try to react with other elements, to gain the noble gas electron configuration to achieve stability. Following Aufbau Principle, the electron occupies the partially filled 3p subshell first, making the 3p orbital completely filled. Thus, it has an electronic configurations of 1s 2 2s 2 2p 6 3s 2 3p 6 and is isoelectronic with H 2 S. Option C: Fluorine gas exists as diatomic molecule F 2 with a total of 2(9) = 18 electrons. 8 electron on the 2nd energy level. Electron Configuration A chlorine ion has 18 electrons (17 e- in a chlorine atom + 1 e- to form the chlorine anion having -1 charge). electron configuration for GaGa: electron configuration for ClCl: electron configuration for PP: electron configuration for CaCa: electron configuration for SS: Because of the addition of one electron, the configuration changes to [Ne]3s^2 3p^7. Examples of isoelectronic species are N 3–, O 2–, F –, Ne, Na +, Mg 2+, and Al 3+ (all have the electron configuration 1s 2 2s 2 2p 6). Chloride is a monovalent ion with -1 charge. Cl-, … What is the electron configuration of chlorine (Cl)? Cl-, so even though it's atomic number is 17, indicating 17 protons and 17 electrons, the charge on the Cl ION is -1 so it has another electron, so it has 18 electrons making the electron configuration … Chlorine-36 is also known naturally and is a radioactive isotope with a half life of about 30,000 years. The electron configurations of silicon (14 electrons), phosphorus (15 electrons), sulfur (16 electrons), chlorine (17 electrons), and argon (18 electrons) are analogous in the electron configurations of their outer shells to their corresponding family members carbon, nitrogen, oxygen, fluorine, and neon, respectively, except that the principal quantum number of the outer shell of the heavier elements has … Thus, its electron configuration is: 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^6 This may also be expressed as: "[Ne]" 3"s"^2 3"p"^6 We and our partners will store and/or access information on your device through the use of cookies and similar technologies, to display personalised ads and content, for ad and content measurement, audience insights and product development.

The chloride ion (Cl-), on the other hand, has an additional electron for a total of 18 electrons. That wouldn't be true if the outer electron in potassium was 3d 1. s- and p-block elements. Then, these electrons are arranged in various energy levels (shells) as person Bohr-Bury scheme. - the first letter of an element is capitalized and the second is a small letter. Electron Configuration and Oxidation States of Chlorine. Except some similarities, Chlorine and chloride has different physical and chemical properties due to the change of one electron. Electron orbitals are differently-shaped regions around an atom's nucleus where electrons are mathematically likely to be located. An atom's electron configuration is a numeric representation of its electron orbitals. Electron Configuration and Oxidation States of Chlorine. Chloride exists in ionic compounds such as sodium chloride, calcium chloride and HCl, which are ionic. So we're writing electron configuration for something with eighteen electrons. This causes an increase in ionic radius for chloride than the chlorine atomic radius.
