When an element is referred to as an ion and not a cation or anion, is the charge negative or positive by default?Naming an AnionThe ions formed from nonmetallic elements are often named by affixing the suffix "
functional group, or molecule is an anion. Like cations, the charge on an anion is indicated using a superscript after a chemical formula. For example, Cl-is the symbol for the chlorine anion, which carries a single
bond: A strong electrostatic interaction between two ions of opposite charge. Ionic bonds are formed between elements with a large difference in electronegativity, so ionic compounds are often composed of a metal (especially an alkali metal or alkaline earth metal) cation and a nonmetal anion. ...
Common table salt is a familiar example of how monatomic ions behave. The monatomic ions that compose salt are sodium (Na+) and chlorine (Cl-). In the solid state, the sodium and chlorine atoms form into a crystal structure in which each sodium atom is surrounded by chlorine atoms and vi...
Nota- bly, the shift of the chlorine atom from para- (cyclogua- nil) to meta-position (Q53) was still tolerated, but at the expense of reduced potency, while the ortho-Cl substi- tution prevented Q52 to acquire an appropriate spatial geometry, likely due to steric hindrance. On the ...
Ion-exchange resins are typically styrene and divinylbenzene copolymers cross-linked to form beads between 0.03mm and 10.mm. The beads are converted into cation-exchange resins through sulfonation or anion-exchange resins through chloromethylation. Ion-exchange resins pick-up positively or negatively ...
Modern definitions of “acid” and “base” (“proton donor” and “proton acceptor”, “producer of cation characteristic of the solvent” and “producer of anion characteristic of the solvent”, “oxide ion donor” and “oxide ion acceptor”, “electron pair acceptor” and “electron-pair ...

A double salt isa salt that contains more than one different cation or anion. ... When dissolved in water, a double salt acts as a mixture of the two separate salts: it completely dissociates into simple ions while a hexaaquo complex does not; the complex ion remains unchanged. ...
They consist of a Halogen anion, also called a halide ion and a cation. ... Examples of Halides are Sodium Chloride, Hydrogen Iodide, Methyl Chloride, etc. Many metal halides are made by the combination of about 80 metallic elements and four halogen. What are halogens and halides? When ...
