ion

 [i´on]
an atom or group of atoms having a positive (cation) or negative (anion) electric charge by virtue of having gained or lost an electron; substances forming ions are called electrolytes. adj., adj ion´ic.
dipolar ion an ion that has both positive and negative regions of charge.
hydrogen ion the positively charged hydrogen atom (H+), which is the positive ion of all acids. See also hydrogen ion concentration.
hydroxyl ion the negatively charged group, OH, present to excess in alkaline solutions.

i·on

(ī'on),
An atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. Ions charged with negative electricity (anions) travel toward a positive pole (anode); those charged with positive electricity (cations) travel toward a negative pole (cathode). Ions may exist in solid, liquid, or gaseous environments, although those in liquid (electrolytes) are more common and familiar.

ion

An electrically charged atom, group of atoms, or molecule. A positive ion is an atom that has lost an electron; a negatively charged ion is one that has gained an electron. See also IONIZATION.

ion

an atom that carries a charge due to loss or gain of electrons.

Ion

An atom or group of atoms that acquires an electrical charge by the gain or loss of electrons.

We therefore, analyzed adipose samples for LPC by tandem mass spectrometry in positive ion mode.
This phenomenon was assumed to be due to the neutralization reaction that happened as a result of the reaction of the stimulated positive ion with the APmg solution; the AP-mg solution was presented in negativeion.14
Both the positive ions and the pre-amplifier resistor help to reduce the effective potential preventing avalanche.
Some of these secondary electrons may be captured by a positive ion in a process known as geminate recombination producing a highly excited state that can dissociate into other products.
So the cathode region is actually a region with a large positive ion concentration (Figure 2).
For the positive ion clusters, similar energies called vertical ionization potentials are calculated.
