WebFeb 1, 2024 · Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero. Once the chlorine gains an electron, however, the total just becomes -1 since there are now 18 electrons and still 17 protons. As a result chlorine is a negative charged ion. It is written as: Cl -.

WebChlorine gains an electron, leaving it with 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full. WebEach chlorine atom has 7 valence electrons so 21 of the 24 total electrons come from the Cl atoms. That leaves 3 valence electrons for Y, which confirms that Y is a group 3A element. B Choose a likely identity for X, Y, and Z in these structures. Be N F O B C O ZCl2 WebExplanatioonic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.n: 20. gabapentin for nerve pain in leg
