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. ...

What are the cation, anion, and formula for Copper(II) Nitrate? What is the formula for the compound copper(I) iodide? Write the chemical formula for the following compounds: A) ammonium thiocyanate B) manganese(IV) sulfide Go from the formula to the name or from the name to the formula...
Trypolium bromide is present in nature as a salt which contains a trypolium cation and a bromine anion. Since, it contains ions so it isan polar compound. As we know that like dissolves like. Therefore, trypolium bromide being a polar compound will be soluble in a polar solvent like water...
Ionic compounds are compounds composed ofions, 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...
(the second longest period) of the periodic table. Tungsten is mainly a hexavalent cation in nature, and its ionic radius is 0.68×10-10m. Because W6+ has a small ion radius, high electricity price, strong polarization ability, and is easy to form complex anions, tungsten is mainly in ...
In some cases, the creation of a good leaving group, such as a mesylate or a bromine atom, at the δ- or ε-position from the isoxazolidine nitrogen atom can be followed by a spontaneous intramolecular nucleophilic substitution with formation of a cyclic isoxazolidinium salt (see also...
