An ion (/ˈaɪən, -ɒn/) is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.
In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation.
If an atom gains electrons, it has a net negative charge and is known as an anion.
An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion. Because of their electric charges, cations and anions attract each other and readily form ionic compounds, such as salts.
In the case of physical ionization of a medium, such as a gas, what are known as "ion pairs" are created by ion impact, and each pair consists of a free electron and a positive ion.
The word ion is the Greek ἰόν, ion, "going", the present participle of ἰέναι, ienai, "to go". This term was introduced by English physicist and chemist Michael Faraday in 1834 for the then-unknown species that goes from one electrode to the other through an aqueous medium. Faraday did not know the nature of these species, but he knew that since metals dissolved into and entered a solution at one electrode, and new metal came forth from a solution at the other electrode, that some kind of substance moved through the solution in a current, conveying matter from one place to the other.

Plot: Horace, a 8 years old boy, who still believes in Santa Clause, received as a Christmas gift a day at the mall. What ought to be a normal Christmas day turns into an adventure when Horace loses his mother. He mets John, a pickpocket disguised as Santa Clause, who was in the middle of an illegal operation. Unlike the Santas on TV, John doesn't seem to like children. Althought, the boy is convinced that this is the real Santa Clause and tail of it, causing all sorts of trouble as dangerous, as funny. Finally John finds the magic of Christmas and Horace discovers that miracles indeed, occur.

Plot: In 1948, a group of miners finds a gallery full of emeralds in a salt mine in Switzerland, but they are attacked by giant black beetles and only one of them survives. In the present days, the explorer John Palmer is ready to take vacations in Greece with his family when he is contacted and invited by a stranger called Vincent to lead his team in an expedition into a mine in Switzerland. In return, Vincent offers a large amount to John and the cottage nearby a lake and the entrance of the mine for his family to spend the vacation. John accepts the offer, and while leading the group underground in the tunnels, he finds that their ambitious leader Marcel is a very dangerous man. When John meets giant black beetles in the cave, he orders the group to return but Marcel threatens the safety of his family, forcing John to lead the team to the deep location of the emerald mine.

To see all my Chemistry videos, check out http://socratic.org/chemistry Confused about ions? We'll learn the difference between an atom and an ion. Ions are formed because of a net charge on an atom, because the number of protons and electrons do not balance. This means that the atom is no longer electrically neutral, but is a cation or an anion. We also talk about polyatomic ions.

Time will tell who I'm waiting for
Light fell as destiny stole you away
As the tears flowed
When I ran to you, and stayed in the cold
Could've followed you, and destroyed my soul
But I'll love you and forgive you as you'll never know
I'm weary now, if the truth be told
As I ran to you, and stayed in the cold
Though your reasoning bore no light nor hope
