Coming from Engineering cum Human Resource Development background, has over 10 years experience in content developmet and management. Chloride is the resulted anion when chlorine abstracts an electron from another electropositive element. Coming to your point, the electron configuration of neutral atom of Cl is [Ne]3s^2 3p^6. 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 D: Oxygen atom has 8 electrons and O 2-ion will thus have 8 + 2 = 10 electrons. When chlorine gas is dissolved in water, it forms hydrochloric acid and hypochlorous acid, which are highly acidic. The p orbital can hold up to six electrons. Therefore we have (still incorrect) 1s 2 2s 2 2p 6 3s 2 3p 6 3d 9 4s 2. • Since there is an additional electron in the chloride ion than the atom, the ionic radius differs from the atomic radius of chlorine. Yahoo is part of Verizon Media. This causes an increase in ionic radius for chloride than the chlorine atomic radius. The answer my book gives is [Ar] 3d^2. Chloride has 18 electrons compared to seventeen electrons of chlorine, and both have seventeen protons. Isobars have different chemical properties because they have different atomic numbers & their electronic configuration is different. The electronic configuration for Cl-can, therefore, be designated as 1s 2 2s 2 2p 6 3s 2 3p 6. Atoms and ions that have the same electron configuration are said to be isoelectronic.

Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure.The chemical symbol for Chlorine is Cl. Electron Configuration To use electron affinities properly, it is essential to keep track of sign. When entering the charge for an ion, it can be entered as +2 or 2+, i.e. rite the electron configuration for the following ion. Be Mg Cl Ni In Irregular Electronic Configurations Expected Cr Ar4 s 2 3 d 4 Cu from CHEM 110 at University of Nebraska, Lincoln 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 … The elements in Group 1 of the Periodic Table all have an outer electronic structure of ns 1 (where n is a number between 2 and 7). 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^6 OR "[Ne]" 3"s"^2 3"p"^6 The electron configuration of a chlorine atom ("Cl") is as follows: 1"s"^2 2"s"^2 2"p"^6 3"s"^2 3"p"^5 But a chlorine ion ("Cl"^-) has acquired a "(1)-" charge as a result of gaining 1 electron. However if you are asking about the ION, so you have to consider the charge. Electron configuration of Chlorine is [Ne] 3s2 3p5. Please help? The next six electrons will go in the 2p orbital. For example, chlorine (atomic no 17) can accept one electron to form Cl –. The electron configuration of chloride is 1s2 2s2 2p6 3s2 3p6.

Use the element blocks of the periodic table to find the highest electron orbital. I don’t understand what … We'll need to know how many sublevel is present in each energy level, and in turn, how many electrons each sublevel can accommodate. 2. In simplified form, I got [Ar]4s^2. An atom's electron configuration is a numeric representation of its electron orbitals. Electron Configuration: The electronic configuration of an atom represents the packing of electrons in the orbitals of the atom. The atomic weight of chlorine is 35.453 amu. This program determines the information shown below for either an atom or an ion. Electron configurations describe where electrons are located around the nucleus of an atom. The shorthand electron configuration begins with the symbol of the noble gas having the closest lower atomic number (the noble gas in the row above the element that you are writing the configuration … Electron Configurations.
