Almost all seen the commercials so-called "chandeliers Chizhevskogo" from which the negative ions in the air are increasing quantitatively.But after school, not all do remember the very definition of the concept.Ions - charged particles is, lost their neutrality inherent in the normal atoms.And now a little more.
«Wrong" atoms
As you know, a great number in the table of Mendeleev, related to the number of protons in the nucleus of an atom.Why do not the electrons?Because the number and completeness of electrons though influences on the properties of the atom, but does not specify its fundamental properties associated with the nucleus.Electrons can not miss, and may be too much.Jonah - it is just atoms with the "wrong" number of electrons.And, paradoxically, they have called a lack of positive electrons, and the negative - the excess.
little about the names
As there are ions?It's a simple question - just two ways of education.Or the way the chemical or physical.The result may be a positive ion, which is often referred to as the cation and the negative, respectively anion.Deficiency or excess of charge can be a single atom or molecule of the whole, which is also considered to be a polyatomic ion specific type.
desire for stability
If ionization of the medium, for example, a gas, it contains a quantity proportional to the ratio of electrons and positive ions.But the phenomenon is rare (in a thunderstorm near the flame), the gas in this altered state, there long.In general, therefore, close to the ground capable of reacting ions air - rare.Gas - the environment is changing rapidly.Once the action of ionizing factors terminated ions meet each other again, and become neutral atoms.This is their normal state.
corrosive liquids
ions in large quantities can be contained in water.The fact that the water molecules - particles in which electric charge is unevenly distributed throughout the molecule, they are dipoles having on one side a positive charge on the other - negative.And when in the water-soluble substance occurs, the water molecules by their electrical poles act on the added substance, ionizing it.A good example is sea water, in which there are many substances in a form like ions.It is known to people for a long time.In the atmosphere above a certain point ions very much, this shell is called the ionosphere.Solar radiation destroys the stable atoms and molecules.The particles are ionized can impart unusual colors around the substance.Example - bright unusual color gemstones.
ions - is the foundation of life, because the basic process of obtaining energy from ATP is not possible without creating an electrically unstable particles, cellular respiration itself is based on the interactions of ions and a variety of chemical processes catalyzed by enzymes, it is due only to the ionization.Not surprisingly, some of the substances in this state a person takes in.A classic example - useful silver ions.
