A positively charged atom; an atom with fewer electrons than protons.

An ion or group of atoms having a positive electrical charge.

A positively charged chemical. For example, calcium (Ca+2), and Magnesium (Mg+2) are cations.

a ion with a positive charge.

An ion carrying a positive charge of electricity. The common soil cations are calcium, potassium, magnesium, sodium, and hydrogen.

A positively charged atom or group of atoms. Cations have more protons (positively charged) than electrons (negatively charged) which gives them a net positive charge.

A positively charged element (nutrient) in the soil. Opposite of cation is anion. Cations are positively charged chemical elements in the soil. Chemically speaking their charge is due to the balance of charge between neutrons (positive) and electrons (negative). Familiar cations that plants need include potassium, calcium, magnesium and iron. These are held onto negatively charged soil particles. Clay and organic materials in the soil have the most negatively charged sites attractive to cations. This is where cations like potassium and calcium are located and stored until released into the soil water for uptake by plant roots.

An ion that bears a positive charge.

an atom missing one or more electrons

an atom or group of atoms that contains more protons than electrons

an atom that has lost one or more electrons and is therefore positively charged

an ion or group of ions having a positive charge in electrolysis

An atom or molecule lacking one or more electrons, and thus carrying a net positive charge.

Positively charged ion. For instance, H+ is a cation.

an ion with one or more positive charges.

An ion carrying a positive electric charge, eg calcium, hydrogen, magnesium, potassium, sodium.

the ion in an electrolyzed solution that migrates to the cathode: Positively charged ion.

Positive ion. Phosphoric acid and PEM fuel cells are "cation-mobile" cells — the cation migrates through the electrolyte toward the cathode.

An ion having one or more positive charges.

When the metal ions in storm water runoff attach themselves to soil particles, which become positively charged atoms.

an atom or molecule which has a positive electrical charge. (see: ion)

A positively charged ion (such as K+).

Neutral atom that loses an electron and becomes positively charged.

Cation - A positively charged chemical.

An ion with a positive electrical charge, such as calcium, magnesium and sodium.

A positively charged ion that in an electrolyte moves toward a negative electrode.

Ions with a positive charge.

The ion which is attracted to the cathode.

A cation is a positively charged ion, i.e., one that would be attracted to the cathode in electrolysis. The opposite of anion.

a positively charged ion that is formed by the removal of an electron from a neutral species, e.g., the removal of an electron (e-) to a neutral sodium atom (Na) forms a singly charged sodium cation (Na+), similarly the removal of two electrons from a neutral magnesium atom (Mg) forms a doubly charged cation (Mg2+).

an ion (charged particle) with a positive charge.

a positively charged ion (eg. Na+(aq.)).

Positively charged ion in solution. When minerals dissolve in water, they form ions that have a tiny positive or negative electrical charge. John Comer, Indiana Geological Survey.

A positively charged ion in a solution.

A positively charged ion, i.e. an ion that is attracted to the negative electrode (anode) in electrolysis (e.g. Ca2+)

A positively charged ion (e.g., Na+, Ca++)

An atom that loses an electron becomes a positively charged ion called a cation.

Positively charged ion that is attracted to a negatively charged cathode.

An ion bearing a positive charge.

An ion with a positive charge, formed when an atom loses electrons in a reaction. The atom now has more protons than electrons.

A positively charged ion that migrates through the electrolyte toward the cathode under the influence of a potential gradient. See also anion and ion.

A positively charged ion (Na+, H+).

A positively charged ion or group of atoms.

A positively charged atom or group of atoms in soil particles that, through exchange with ions of metals in stormwater runoff, enable those metals to attach themselves to soil particles.

A positive ion, which in electrolysis, travels to the cathode and is discharged there.

The positive ion that results when an atom loses one or more electrons. A cation (pronounced "KAT-ie-un") is named after the element of which it is anion and thus is called, for instance, the aluminum ion or the aluminum cation.

An ion of an element or compound with a positive electro-magnetic charge.

cation] an ion with a positive charge.

a positively charged ion. A positively charge ion is cationic. A negatively charged ion is anionic.

Electro-positive ion.

Refers to chemical ions present that carry a positive charge. The common cations present in lakes in normal order of decreasing concentrations follow: calcium (Ca++), magnesium (Mg++), potassium (K+), sodium (Na+), ammonium (NH4+), ferric iron (Fe+++) or ferrous iron (Fe++), manganese (Mn++), and hydrogen (H+).

(cat-i-on) Positively charged ion; ion which, during electrolysis, is attracted to the cathode. Some common cations are calcium, magnesium, sodium, potassium, ammonium, and hydrogen.

a positively charged ion; an example is a sodium ion

a positively charged ion. Examples are sodium and calcium.

Compare with anion. A cation is a positively charged ion. Metals typically form cations.

A positively charged ion (calcium Ca++ or sodium Na+)

A positively charged element or ion. This includes base cations as well as aluminium and hydrogen.

An ion carrying a positive atomic charge.

(cat'-i-on) A positively charged ion. Si4+, Fe2+, Fe3+ and V4+ are all examples of cations.

A positively charged ion in an electrolyte solution, attracted to the cathode under the influence of a difference in electrical potential.

When a salt is dissolved it has two charged molecules: a cation (positively charged), which can behave as an acid, and an anion (negatively charged), which can act as a base. If a surface has a negative charge it is called cationic and can be used to capture positively charged molecules.

An ion that has a positive electrical charge. That is, an atom that has lost one or more electrons. Important to understanding the chemical properties of bogs.

The charged particle in the solution of an electrolyte which, under the influence of an electrical potential, moves toward the cathode. It is the positively charge ion.

An ion that migrates to the cathode in an electrical cell; a positively charged ion.
