cation

A positively charged atom, such as Na+ or K+, which is attracted towards a negative electrode (cathode). An atom which, in solution, takes a positive charge. Unlike charges attract; like charges repel.

Cation

An ion carrying a positive charge due to a loss of electrons. Cations in the body include sodium, potassium, magnesium, and calcium ions.

Isomorphic substitutions can occur in either the tetrahedral ([Si.sup.4+] with [Al.sup.3+]) or octahedral ([Al.sup.3+] with [Mg.sup.2+] or [Fe.sup.2+]) sheets, which yields a net negative charge that is balanced by cations located in the interlayer region.
