This means that all anions (negatively charged ions) are lower in energy than their parent atoms.

An ionizer is a device that disperses negatively (and/or positively) charged ions into the air.

Positively charged ions outside the cell experience a force towards the cathode.

This creates positively charged ions and electrons, known as ion pairs, in the gas.

For example, most metal centers are positively charged ions which exist as salts.

As electrons diffuse, they leave positively charged ions (donors) in the n region.

Before the reaction we had neutral atoms and after the reaction we have charged ions.

It was not obvious that this approach could work, as positively charged ions would all orbit the magnetic field in the same direction.

For example, the electric currents in electrolytes are flows of positively and negatively charged ions.

This specially treated material, which looks something like ordinary kitchen plastic wrap, only conducts positively charged ions.
