In organic chemistry, an iminium cation is a polyatomic ion with the general structure [R1R2C=NR3R4]+. They are common in synthetic chemistry and biology...

temperatures it isomerizes to formic acid. The double ionized ion, CO2−2, is known as the carbonite ion. Schreiner, Peter R.; Reisenauer, Hans Peter (2008). "Spectroscopic...

metal atom and the anion is a nonmetal atom, but these ions can be more complex, e.g. polyatomic ions like NH+ 4 or SO2− 4. In simpler words, an ionic bond...

These polyatomic ions are groups of atoms that are covalently bound together and have an overall ionic charge, such as the sulfate [SO4]2− ion. Each polyatomic...

positively-charged polyatomic ions of the structure [NR4]+, where R is an alkyl group, an aryl group or organyl group. Unlike the ammonium ion (NH+4) and the...

carbonic acid, (H2CO3), characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2−3. The word "carbonate" may also refer to a...

polyatomic ions. Therefore, the name of the metal or positive polyatomic ion is followed by the name of the non-metal or negative polyatomic ion. The positive...

paws ⇔ Cations are pawsitive. Ca+ion: The letter t in cation looks like a + (plus) sign. An anion is a negative ion. (Anegativeion ⇒ Anion). AN OIL RIG...

nomenclature discrepancies exist. This linkage is recognized as a common polyatomic ion, and exists in many molecules. The characteristic structure of any regular...

The nitronium ion, [NO2]+, is a cation. It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH4]+. It is created by the...

mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, also...

bleaching of natural substances. The thiosulfate ion is tetrahedral at the central S atom. The thiosulfate ion has C3v symmetry. The external sulfur atom has...
