Definition of Positive Ions, Characteristics, and Examples

Ions are basically around us right now and maybe even we are not aware of them, even though they are very possible to influence the way we feel and even affect the health of a person’s life.

In general, there are two types in terms of ions, namely positive ions and negative ions, but this article will explain related to the notion of positive ions, characteristics, and examples in human life.

Positive Ion

Positive ions are electrically charged atoms, or groups of atoms, formed by the loss of one or more electrons. The number of protons does not change but the reduction in electrons gives the atom a positive charge. Positive ions are also known as cations .

Positive ions in the air are usually carbon dioxide molecules that have been stripped of electrons. These have been shown to have negative effects on our bodies when we are over-exposed to them.

It especially occurs in the lungs and respiratory tract, but our immune system can also be affected. This is because positive ions are so small that they are absorbed directly into our bloodstream from the air we breathe.

The Positive Ion Feature

In general, positive ions which are often known as cations have the following characteristics, among others;

  1. Cation (+), derived from the Greek word (káto), which means “down”, which can be interpreted as ions with fewer electrons than protons, thus giving a positive charge.
  2. Based on electron properties as previously described, cations are smaller than the parent atom or the corresponding molecule because of the smaller size of the electron cloud. A special cation (ie hydrogen) does not contain electrons, and thus consists of one proton – much smaller than its parent hydrogen atom.
  3. Measured by its ionic radius, the cation is smaller. Cations have radii less than 0.8 × 10-10 m (0.8 Å).
  4. An excess of positively charged ions in our environment can contribute to fatigue and lack of energy, tension, anxiety and irritability. Positive ions in the air have even been investigated as factors that cause asthma, allergies, migraines and depression.
  5. In nature, positive ions are usually formed by strong winds, dust, humidity, and pollution and are at their highest levels just before an electric storm.
  6. At home, fluorescent lamps and electrical appliances such as televisions and microwaves are big positive ion generators, as are fibers in carpets, curtains and upholstery. Air conditioners, fan heaters, hair dryers and clothes dryers are also strong sources of positively charged ions.
  7. The type of element is metal, which is a material which, when newly prepared, polished, or cracked, shows a sparkling appearance, and conducts electricity and heat relatively well.

Metals are usually malleable (can be forged into thin sheets) or resilient (can be stretched onto cables). A metal can be a chemical element such as iron; alloys such as stainless steel; or molecular compounds such as sulfur nitride polymer.

Examples of Positive Ions

For some examples included in positive ions, including;


Silver is a chemical element with the symbol Ag (from Latin argentum, derived from the Proto-Indo-European language: “shiny” or “white”) and atomic number 47. Soft, white, sparkling transition metals exhibit the highest electrical conductivity, conductivity thermal and reflectivity of any metal.

This metal is found in the earth’s crust in the form of pure free elements (“real silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargirrit. Most silver is produced as a by-product of copper, gold, lead, and zinc refining.


Ammonium is a positively charged polyatomic ion with the chemical formula NH + 4. This is formed by protonation of ammonia (NH3). Ammonium is also the general name for substituted amine or positive protonation and quaternary ammonium cations (NR + 4), where one or more hydrogen atoms are replaced by organic groups (indicated by R).

Well, that’s a series of articles that we have written in full to all readers related to the understanding of positive ions , characteristics, and examples. Hopefully, through this material can provide insight and increase knowledge for all readers. Thanks,
