a cation is a positvely charged atom, and if an element is positive, then you add "ion" to the end of the element. for example, sodium becomes sodium ion or Na1+ A Cation is a positive ion, that is, one that has fewer than four valence electrons. Some examples of elements that form cations are: * Lithium (Li) * Beryllium (Be) * Boron (B) * Sodium (Na) * Magnesium (Mg) * Aluminum (Al) * Potassium (K) * Calcium (Ca)
cations are positively charged ions such as Na+, H+, K+, Mg2+, Al3+ etc.
A cation is a positively charged Ion
Ca2+
The cation of lithium is Li+.
An oxonium cation is a polyatomic cation with a charge of +1 with a central oxygen bonded to three groups or elements Examples:- H3O+ is the oxonium cation, (C2H5)3O+ is the triethyloxonium cation.
metals
Basically mecuric ions exist in solution as Hg2+,Hg22+ <P> <P>Neither, in it's natural state. Mercury (Hg) is an element, and exists as a neutral atom, unless it combines with other elements. In this case, it combines with negative elements (for example chloride -Cl) and then it has a positive charge (Hg)++(Cl-)2. Then, it is a cation.</P>
A cation is a positive ion
Divalent cation: Ca2+ Trivalent anion: (PO4)3-
The cation of lithium is Li+.
An oxonium cation is a polyatomic cation with a charge of +1 with a central oxygen bonded to three groups or elements Examples:- H3O+ is the oxonium cation, (C2H5)3O+ is the triethyloxonium cation.
A binary compound will contain atoms of only two elements. If the binary compound only contains nonmetal elements its name will begin with the prefix tetra.
The cation is Na+.
A Cation is a positive ion formed after removal of electron(s). For example, Fe^+2

A cation is a positive ion
The name of a cation in an atom is electron. Cation refers to an ion of negative charge. Since electron is also of the same charge, the cation is electron.
The ammonium ion, NH4+, is the only polyatomic cation.
