What is Ionization?

Ionization is when an atom or molecule gains either a positive or negative charge. It can occur in one of two ways: first, when electrons are either gained or lost by a particle; second, when one atom or molecule combines with another atom or molecule that already has a charge. The charged particle itself is called an ion. Ions that are positively charged are called cations, and ions that are negatively charged are called anions. As well, ions made up of one atom are called monatomic ions, and ions made up of multiple atoms are called polyatomic ions.

Ionization often occurs because of the number of electrons a particle has. Particles with paired (even-numbered) electrons are more stable than those with unpaired electrons; atoms with filled electron shells are also more stable than those with only partially-filled shells. When particles collide and interact, electrons from one atom might be pulled to another in order to give it an even number of electrons or to fill one of its electron shells. An atom with an odd number of electrons and only a single electron in its outer shell would tend to give up its electron in such an interaction. Particles charged through ionization tend not to be as stable as those that naturally have their electron shells filled with an equal number of protons and electrons.

Ionization energy

Ionization energy, which is the amount of energy that is required to separate an electron from an atom, is important for physics and chemistry. By ionizing an atom, an electron is removed, and a positive ion is added, changing the entire structure of the atom. When ionized, the atom cannot make normal bonds, so it can be used for entirely different purposes, depending on the scientists needs. Some atoms have different ionization energy levels, at which time the ionization is referred to according to the order of energy. The ionization has a special energy value called electronvolts.

Every atom has at least one electron, and this electron gives the atom a negative charge. To ionize the atom means to remove one or more electron to give the atom the positive charge of an ion. Adding an unspecified amount of energy to an atom will not yield proper results and can either lead to no electrons or too many electrons fleeing the atom. One way of calculating ionization energy is to run a current through the atom until it emits light.

Bipolar Air Ionization

Millions of ions are formed as air passes over the ionization tubes. These ions travel through the duct system and out into the treated space attacking pollutants where they are most problematic – where we work, learn, live, eat, and sleep.

Much like sunlight does in the atmosphere, the Bipolar Air Ionization technology produces a natural bio-climate rich in active oxygen molecules, otherwise known as ions. The bipolar air ion technology creates a measurable and controllable quantity of positive and negative oxygen ions. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition. These unstable ions provide the following benefits:

Particle Reduction

Airborne particles are charged by the ions through ionic bonding. These charged particles stick together increasing their size allowing them to be easily removed by even low grade filters. Additionally, particles are the vehicles that transmit bacteria cells from person to person. As the ions cause increased particle size, the result is less bacteria in the breathing zone.


As they divide in the split zone, bacteria and mold spores bond with active oxygen molecules and are oxidized and destroyed. The bacteria and mold can no longer multiply.

Odor Neutralization

Odorous gases and aerosols oxidize on contact with active oxygen molecules. Odors, especially of an organic origin, are quickly eliminated.

VOC Control

Volatile Organic Compounds (VOCs) are emitted as gases where there is carpeting, building materials, furniture, office equipment, cleaning agents, paints, glues, solvents or pesticides. The ions trade electrons with these VOCs breaking down their molecular structures into less harmful ones.

Health Benefits

Human and animal lungs absorb oxygen more efficiently from clean ionized air, enhancing general health and well-being. Alertness and concentration are improved.
