What is an ion ?
Not many people are well versed in a variety of terms, theories and laws of physics and chemistry.And some may be just beginning to study these disciplines.Therefore, certain terms may be unknown or forgotten.For example, the word "ion" is familiar to so many people, however, let us remember that this ion and what properties it possesses.
What is ion
word and concept of "ion" comes to us from the Greek language and means "coming".Ion is a charged particle.Consequently, the ion can have both positive and negative charge.Charged particles can be either a single atom or molecule or free radical.The charge in this case is a multiple of the electron charge.
In a free state ions are found everywhere in any aggregate state of matter.They can be found in gases, liquids, alloys crystals and plasma.
If negative ion, it is called an anion, and a positive charge is called a cation.These names were introduced scientist Michael Faraday, who discovered the ions.
term "ion" was also introduced by physicist and chemist Michael Faraday in 1834, when he studied the effects of electric current on a variety of aqueous solutions.It was then that he concluded that the electrical conductivity of various alkaline, acidic and saline solutions depends on the movement of specific particles, which he called ions, and divided into positive and negative in charge.
ions have some basic physical properties:
- ions are active substances and interact with atoms, molecules, free radicals and ions of the same.They are involved in a variety of reactions.
- In an electric field the ions carry electricity to the right electrodes of opposite charge.
- ions in living organisms also play a huge role, conducting nerve impulses.
- ions can act as a catalyst or intermediate species in chemical reactions.
- Ionic reactions in electrolyte solutions occur instantaneously;
- positive hydrogen ions are protons in physics.Protons and neutrons form the nuclei of atoms all.Get a proton can be ionization of the hydrogen atom.
