Ion

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.

History of discovery

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.

Ion (DC Comics)

Ion is a fictional character, a DC Comics superhero. Created by writer Judd Winick and artist Dale Eaglesham for Green Lantern vol. 3 #142, Ion was devised as the new superhero identity for Green Lantern protagonist Kyle Rayner. It was later revealed to be able to form mutualism with a host, bestowing its power to a host willingly. This followed a similar retcon as Parallax, originally the new supervillain alias of Hal Jordan, which was revealed to be a parasitic embodiment of fear in the 2004–2005 miniseries Green Lantern: Rebirth.

Fictional character biography

As soon as sentient beings developed willpower, Ion was born from the green wavelength of the so-called "emotional spectrum". Its existence has been kept a secret for eons, and it resided in the Central Battery on Oa to keep Parallax, the parasitic fear entity also imprisoned there, in check, as well as granting the Guardians of the Universe, Manhunters, The Green Glob, Halla's, and then The Green Lantern Corps a portion of its vast powers. After Hal Jordan, under the influences of Parallax and Sinestro, destroyed the Central Battery, Ion, along with Parallax and Sinestro, were set free. After wandering throughout the cosmos, it eventually settled within Kyle Rayner as its host.

Ion (name)

Ion is a masculine given name. The name form in English corresponds to two different and unrelated names from different original languages.

The first name is the Greek,Ἴων, Iōn, after the mythical founder of the Ionians; the modern (demotic) Greek equivalent of the name is Ionas. The source of this is the Hebrew Yavan, alternatively transliterated as ι-o-ν (Yut Vav/digamma Nun), with each letter corresponding to its appropriate counterpart.

The second name is the Romanian Ion which is equivalent to the English name John and has the same etymology as "Jon", tracing back the Hebrew name Johanan; Ion can also be a surname in Romanian. Another variant is Ioan. A common diminutive is Ionel. Its female form is Ioana. The surname Ionescu derives from Ion.

Ion as a given name

Disco (software)

Disco is an application for Mac OS X developed by Austin Sarner, Jasper Hauser and Jason Harris.

The software is an optical disc authoring utility, which allows users to burn CDs and DVDs with multisession support, disc duplication, burning VIDEO_TS folders, disc spanning as well as a searchable disc index, dubbed Discography. Disco also features an interactive "3D smoke" animation which is visible when burning. This smoke responds to microphone input, as well as mouse input, causing perturbations in the smoke effect.

Disco was designed as a low-cost alternative to the popular Mac OS X optical disc authoring application, Roxio Toast.

Since its launch in 2007, Disco was available as shareware, requiring users to purchase a license after burning seven discs with it on a single computer. In July 2011, a free license code to activate the application was published on its official website, effectively making the application available as freeware.

Disco (film)

Disco is a French film directed by Fabien Onteniente, which was released on 2 April 2008, with Franck Dubosc as "Didier Travolta" in the main role.

The main subject of this movie is the rebirth of disco music at the mid-2000s in a town of France. The film is at first humorous, with a lot of clichés about Saturday Night Fever, but it doesn't disparage the disco culture at any time. In fact, all the people involved in this film are fans of disco, dance and funk music.

The soundtrack to the film contains a cover version of the Bee Gees' "Night Fever" performed by Australian singer and songwriter Tina Arena.
