Use the word ion in a sentence?

Answer 1

An ion is a chemical unit that carries an electric charge. An ion may include a single atom or a group of atoms that are chemically bonded together. The first may be called a monatomic ion and the second may be called a polyatomic ion. The amount of electric charge is always some small whole number times the charge on an electron, because ions are generated by the transfer of electrons from one neutral atom or group of atoms to another.

As for lightning, producing a relatively small thunder clap, a potential energy difference of about 260 million or mega volts is required, and the huge potential breaks down the air molecules into ions.

Polyatomic ions are also called radicals.* An example is OH with a valence of minus one, consisting of one oxygen atom and one hydrogen atom per individual radical. There are basically two kinds of ions, anions and cations. The former pertains to atoms the outer electron shell of which are nearly complete, e.g. chlorine, bromine, and iodine. These atoms each accept a single electron from the atoms of substances of metallic nature.** Cations form when the atoms of metallic substances donate one or more electrons to complete the outer electron shells of the atoms of substances capable of forming anions. This phenomenon occurs in water, where the ions end up in solution. Thus, in the case of sodium chloride solution, we end up with ions of chloride, called, as a group, chloride, in solution with complete outer shells but with a single extra electron on each atom such that each atom has a minus 1 charge. Additionally, in the same solution, we have sodium ions that have each given up an electron and each have a plus 1 charge.

A solution of sodium hydroxide contains equal numbers of sodium ions and hydroxide radicals. Sodium sulfate contains two sodium ions for each sulfate radical, as the latter has a minus 2 charge. (Each sulfate radical contains one sulfur atom and four oxygen atoms.)

*Note that there is another meaning of "radical", particularly in organic and mechanism chemistry: A chemical unit that contains one unpaired electron.

**Note that nonmetals of column 16 in a wide form Periodic Table can similarly accept two electrons, and nitrogen and phosphorus can accept three electrons to form monatomic anions.

Answer 2

The ion gained an electron and became negatively charged.
