cation

listen to the pronunciation of cation
English - English
The ion in an electrolyzed solution that migrates to the cathode
A positively charged ion; -- opposed to anion
Atom or group of atoms carrying a positive electric charge, indicated by a superscript plus sign after the chemical symbol. Cations in a liquid subjected to an electric field collect at the negative pole (cathode). Examples include sodium (Na^+), calcium (Ca^2+), and ammonium (NH4^+; see ammonia). See also ion; Compare anion
A positively charged ion (Na+, H+)
(chem) A positively charged ion (Greek, katienai, to go down)
- an ion with a positive charge
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 positive ion
An ion with a positive electrical charge, such as calcium, magnesium and sodium
A positively charged ion [back] [top]
A positively charged ion, such as the Mg2+ ion
A positively charged chemical substance
An ion with a positive charge
An electro-positive substance, which in electro-decomposition is evolved at the cathode; opposed to anion
positively charged ion Common soil cations include calcium, magnesium, sodium, potassium, and hydrogen
A positively charged °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
A positively-charged ion
An atom or group of atoms with a positive charge
{i} ion with a positive charge
a positively charged atom or group of atoms, or a radical which moves to the negative pole (cathode) during electrolysis
Positively charged ions such as sodium (Na+) or ammonium (NH4+)
An ion bearing a positive charge
A positively charged ion
Positively charged ion
a particle that carries a positive electrical charge The cation gets this positive charge from losing negatively charged electrons
An ion carrying a positive charge
cation exchange
(Kimya) A chemical process in which cations of like charge are exchanged equally between a solid, such as zeolite, and a solution, such as water. The process is often used to soften water
cation exchange capacity
(Bilim, İlim) In soil science, cation exchange capacity (CEC) is the capacity of a soil for ion exchange of positively charged ions between the soil and the soil solution. A positively-charged ion, which has fewer electrons than protons, is known as a cation due to its attraction to cathodes. Cation exchange capacity is used as a measure of fertility, nutrient retention capacity, and the capacity to protect groundwater from cation contamination
radical cation
a positively charged radical ion
cations
plural of cation
cations
Ion with a positive charge
cations
Think chemistry class When an atom or molecule has more protons (positively charged particles) than electrons (negatively charged particles), it has an overall positive charge and is called a cation Many minerals, when in solution (that is, dissolved in water), carry a positive charge Clay particles are negatively charged and will attract any cations in solution that are near it; just like two magnets of opposite charge are attracted See also clay
