n.名词 noun

Physics, Chemistry.
- : an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation , which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion , which is created by an electron gain and is attracted to the anode. The valence of an ion is equal to the number of electrons lost or gained and is indicated by a plus sign for cations and a minus sign for anions, thus: Na+, Cl−, Ca++, S=.
- : one of the electrically charged particles formed in a gas by electric discharge or the like.

Examples

Each molecule of salt contains a pair of ions, atoms with an electrical charge.
The company plans to get around this by instead shuttling the ions themselves around the system.
The other was a reformulation of the material that carries ions between the battery’s cathode and its anode.
Those ions can trigger the mucus to emit bursts of blue light, the team reports.
Lithium salts provide the ions that move through the new electrolyte.
I have previously drawn attention to the cargo aboard Flight 370, which included a large consignment of lithium-ion batteries.
Last week it made five recommendations directed at the testing and certification of lithium-ion batteries.
Lithium-ion batteries will further increase underwater performance.
How can this saga of the lithium-ion batteries be tied to the fate of Flight 370?
A month after that announcement, unaccustomed daylight was forced upon the lithium-ion battery industry.
A merry, happy time the children had, and on reaching Ion the little ones were ready for their supper and bed.
At Ion Grandma Elsie lay quietly sleeping, her three daughters watching over her with tenderest care and solicitude.
In other words, five hydrogen ions passed to the right, while one chloride ion passed to the left.
That is, different concentrations of hydrogen-ion or of hydroxide-ion are required to change their colors.
The second table gives, similarly, the concentrations of hydroxide-ion required to produce the changes of tint indicated.
