Cation A positively charged ion that migrates naturally to a cathode. 

Cation A positively charged ion that is, an ion in which the atom or group of atoms has fewer electrons than protons. 

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

CATION. A positively charged ion. Cations are those ions that are deposited, or which lend to be deposited, on the cathode. They travel in the nominal direction of the current. In electrochemical reactions they are designated by a dot or a plus sign placed above and behind the atomic or radical symbol as H or H+. the number of dots or plus signs indicating the valence of the ion. 

An ion is an atom or group of atoms with a net electrical charge. Anions are negatively charged ions that are formed by addition of electrons. Cations are positively charged ions that are formed by the loss of electrons. 

Cation (Section 1.2) A positively charged ion that results from a neutral atom losing one or more electrons. 

Cation—positively charged ions that migrate to the cathode in a galvanic cell. 

A positively charged ion is electron deficient and acts as an electrophile. The atom that bears the positive charge is the electrophilic centre. In case of a carbocation (Following fig.), this is the carbon atom. Some molecules (e.g. the allylic cation) are able to delocalise their positive charge between two or more atoms in which case all the atoms capable of sharing the charge are electrophilic centres ... 

The precise reactivities of various types of carbenium ions (free, paired, and aggregates) are not known, but it seems that the differences in reactivities are not very large. This may be due to solvation effects, which are similar for all types of carbocations, and also due to the large size of the counterions which interact weakly with the cations. A positive charge in carbocations is located partially on the sp2-hybridized C atom and is widely delocalized over the /3-protons and substituents, especially in the case of aromatic and alkoxy a-substituents. 

Note that the sodium atom has one 3s valence electron it differs from the noble gas neon by that single valence electron. If sodium loses this outer valence electron, the resulting electron configuration will be identical to that of neon. Figure 8-1 shows how a sodium atom loses its valence electron to become a posihve sodium ion. A positively charged ion is called a cation. 

An electrolyte is a salt that splits into ions when placed into water. An ion is an electrically charged particle that is either positively or negatively charged. A positively charged ion is called a cation and a negatively charged ion is called an anion.
