salt in the liquid state, largely made of ions and short-lived ion pairs (while ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules)

a charged chemical species composed of two or more atoms covalently bonded or of a metal complex, that can be considered to be acting as a single unit

A polaron is a quasiparticle used in condensed matter physics to understand the interactions between electrons and atoms in a solid material. The polaron concept was proposed by Lev Landau in 1933 and Solomon Pekar in 1946 to describe an electron moving in a dielectric crystal where the atoms displace from their equilibrium positions to effectively screen the charge of an electron, known as a phonon cloud. This lowers the electron mobility and increases the electron's effective mass.

ion consisting of one atom

device or process or technique that creates charged atoms and molecules (ions)

Formula for lattice energy

gas ionisation process where free electrons are accelerated by an electric field, collide with gas molecules, and consequently free additional electrons

In organic chemistry, methenium (also called methylium, carbenium, methyl cation, or protonated methylene) is a cation with the formula . It can be viewed as a methylene radical (:) with an added proton (), or as a methyl radical (•) with one electron removed. It is a carbocation and an enium ion, making it the simplest of the carbenium ions.

beam of charged atoms (ions)

ratio of electric charge to radius of an ion

Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water, thereby removing trace minerals that function as anions and cations. By itself, it does not remove other contaminants, including pathogens, organic compounds, or dissolved gases. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically regenerated mixed beds, by operating continuously without chemical regeneration.
