In chemistry, a positively charged ion. Pronounced cat-I-on. A cation is as opposed to an anion, which is a negatively charged ion.

An ion carrying a positive atomic charge.

A positively charged ion.

(kat-eye-on) An ion with a positive charge, produced by the loss of one or more electrons.

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

An ion that has a positive electrical charge. That is, an atom that has lost one or more electrons.

1834, from Greek kation "going down," neuter present participle of katienai "to go down," from kata "down" (see cata-) + ienai "to go" (see ion). Proposed by th [..]

Neutral atom that loses an electron and becomes positively charged.

A positively charged ion.

An ion carrying a positive charge of electricity. Soil cations include calcium Ca++ and sodium Na++.

A positively charged ion.

A positively charged ion. Plant nutrient examples include calcium (Ca++) and potassium (K+). See anion.

A positively charged ion. The most commonly found cations in soil waters include sodium, potassium, calcium and magnesium.

an ion carrying a positive atomic charge. Many key soil nutrients employ cations. Cation Exchange Capacity: how well a soil hosts exchanges of cations between its minerals and its plant roots. In general, soils high in clay and organic matter carry a negative charge that retains plant nutrient cations against leaching away. High CEC usually correla [..]

An ion with more protons than electrons.

n. a positively-charged ion which is characterized as having more protons and fewer electrons. Examples include the sodium ion (Na) and the potassium ion (K). Compare anion.

Ion that is positively charged. See anion.

  A positive ion.

A positively charged ion, such as a potassium or sodium ion. Compare anion.

An anion is a positively charged ion. See also Anion and Ion Exchange.

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

A negatively charged ion, resulting from dissociation of molecules in solution.

(n) a positively charged ion

Particle with positive charge; reactions between anions and cations create electrical forces.

A positively charged ion (Lessons 8, 10, 11)

A positively charged ion; cations in the body include sodium, potassium, and magnesium.

An ion with positive charge is designated cation. It receives this designation according to the "cathode", because it is attracted by the cathode in an electric field.          

A positive ion.

Positively charged ions including potassium, calcium, magnesium, and hydrogen.

Particles in the electrolyte of a galvanic cell carrying a positive charge and moving towards the cathode during operation of the cell. See also anion

An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.

A positively charged ion, i.e. hydrogen (H+).

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

a positively charged atom or group of atoms, or a radical which moves to the negative pole (cathode) during electrolysis.

a positive ion.

Illustrated Glossary of Organic Chemistry Cation: An atom or molecule with a positive formal charge. Na+ Sodium cation    Methyl carbocation     Trimethyl phenyl ammonium cation

A positively charged ion or group of atoms.

a positively charged ion.

is a positively charged chemical. For example, calcium (Ca+2

Atom or atom group positively charged (positive ion)

A positively charged ion in an electrolyte solution, attracted to the cathode under the influence of a difference in electrical potential. Sodium ion (Na+) is a cation.

Positively charged ions including potassium, calcium, magnesium, and hydrogen.

Positively charged ions such as sodium (Na+) or ammonium (NH4+).

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

An ion carrying a positive atomic charge.

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

Neutral atom that loses an electron and becomes positively charged.

An atom that has lost one or more electrons; a positively charged ion.

A positively charged ion (such as K+, Na+, NH4+).

a positively charged ion, usually found dissolved in water, such as calcium (Ca++). Read more information about measuring water quality.

A positively charged ion. Plant nutrient examples include calcium (Ca++) and potassium (K+). See anion.

A positively charged atom or radical.

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