An electrically charged atom or group of atoms. If an atom or molecule gains an electron - it becomes a negatively charged anion, or if it loses an electron it becomes a positively charged cation.
(Humans as organisms) positively- or negatively-charged particles - eg positively charged hydrogen, sodium and potassium atoms. Ion charge helps determine a substance's acidity or alkalinity
Electrically charged element, group of elements or particle. Many of the salts in the soil solution exist as ions.
A charged particle consisting of an atom stripped of one or more of its electrons.
Ion was an ancient Greek tragic poet, a native of Chios, who lived about 450 BC. His tragedies were represented at Athens with great applause, and he is greatly commended by Aristophanes, Athenseus, etc.Found on http://www.probertencyclopaedia.com/browse/CXI.HTM

An ion is a charged atom or group of atoms. The charge occurs from a surplus or deficiency of electrons.Found on http://www.probertencyclopaedia.com/browse/GI.HTM
An atom or molecular fragment that has a positive electrical charge due to the loss of one or more electrons; the simplest ion is the hydrogen nucleus, a single proton.

An ion is a charged Atom or molecule. The ion is charged because the number of Electrons do not equal the number of Protons in the atom or molecule. If the atom or molecule contains an excess of electrons it will be negatively charged (e.g. OH-) where as if it is depleted in electrons it will have a net positive charge (e.g. H+).

- a particle that is electrically charged (positive or negative)Found on http://www.webdictionary.co.uk/definition.php?query=ion
An atom with one or more electrons in surplus or deficit. Because each electron carries a unit negative charge, if there is a surplus of them the overall atomic charge is a net negative (making the ion in question an anion), and if there is a deficit of them the overall atomic charge is a net positi

An ion is an electrically charged atom or molecule. It may comprise one or more atoms and be positively (cation) or negatively (anion) charged. The number of positively charged core modules (protons) in atoms is identical to the number of negatively charged electrons which encircle the core. An atom is outwardly electrically neutral. An ion is char...Found on http://www.encyclo.co.uk/local/20514
An ion is an electrically charged atom. In a neutral atom, the number of protons in the nucleus is balanced by the number of electrons around the nucleus. If an electron is knocked away from the nucleus (perhaps as a result of radiation), then the atom will be left with a net positive charge. The process of creating ions is called ionisationFound on http://www.users.zetnet.co.uk/computing/MainPage/SecDepts/Physics/Resources
