In a dilute solution of sulphuric acid, the positive ion is of hydrogen, while the negative ion is the (SO4) or sulphion.
The positive ion is any sort of an atom or molecule which has become positively electrified in this way.
The toxicity of the positive ion was again set forth by Copeland and Kahlenberg .
Under the former circumstances it becomes a positive ion, and under the latter a negative ion.
If the force on the positive ion is from A to B, the plate B will receive a positive charge of electricity.
The loss of the small negative charge carried in the electron leaves the atom positively electrified or creates a positive ion.
1834, introduced by English physicist and chemist Michael Faraday (suggested by the Rev. William Whewell, English polymath), coined from Greek ion, neuter present participle of ienai "go," from PIE root *ei- "to go, to walk" (cf. Greek eimi "I go;" Latin ire "to go," iter "a way;" Old Irish ethaim "I go;" Irish bothar "a road" (from *bou-itro- "cows' way"), Gaulish eimu "we go," Gothic iddja "went," Sanskrit e'ti "goes," imas "we go," ayanam "a going, way;" Avestan ae'iti "goes;" Old Persian aitiy "goes;" Lithuanian eiti "to go;" Old Church Slavonic iti "go;" Bulgarian ida "I go;" Russian idti "to go"). So called because ions move toward the electrode of opposite charge.
ion i·on (ī'ən, ī'ŏn')
An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons.
