Ions anions
WebVarious ion-exchange processes have been developed to modify glass surfaces. For example, U.S. Pat. No. 3,844,754 discloses a process for strengthening a glass article by forming a solid layer of an alkali metal salt on a surface of the glass, and then heating the glass article and the solid layer at an elevated temperature to carry out an exchange of … WebAn ion is an atom (or group of atoms) with an electrical charge. Anions are one of the two types of ions. The other type is called a Cation, having a positive charge. In many …

WebDefine ions, cations and anions Predict the charge of an anion or cation based upon the location of the element in the periodic table Ions of Elements In ordinary chemical reactions, the nucleus of each atom remains unchanged. WebAn anion is an ion that has gained one or more electrons, giving a net negative charge. Because electrons are added to form an anion, the anion of an atom is bigger than the neutral atom. Examples of anions include the following: Chlorine: Cl – Hydroxide: OH – Iodide: I – Dichromate: Cr 2 O 7-2 Oxide anion: O -2 Sulfate anion: SO 4-2
