The NMR spectrum established that it was nonclassically bridged (the first stable non-classical ion observed).

The triflate anion, CFSO is an extremely stable polyatomic ion, being the conjugate base of triflic acid (CFSOH), one of the strongest acids known.

The noble gases-including helium-can form stable molecular ions in the gas phase.

Replies: Zunaria, Electron affinity is the energy change that occurs when an neutral atom in the gaseous state acquires an electron to form a stable negative ion.

PG Research Foundation, Darien, Illinois Joseph, Losing or gaining an electron to form a stable ion is a characteristic of "ionic" bonds.

It is one of the most stable diatomic ions known and forms a wide range of complexes.

All elements in this column have one thing in column; their most stable ion is a cation with a charge of +1.

Cations of elements which only form one stable ion are given the same name as the element.

Most lithophile elements form very stable ions with an electron configuration of a noble gas (sometimes with additional f-electrons).

It features the vanadyl ion, VO, which has been called the "most stable diatomic ion."
