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>
Yes, it is a cation
it is called a cation and a negitively charged ion is an anion
A cation is a postitve ion. Sodium (Na+) is a postitive ion. Therefore, Na+ is a cation. It's definitional.
Anion is a negative ion (Cl-) and cation is a positive ion (Na+).
A cation is a positive ion
An ion with a positive charge is called a cation, and has a superscript + sign to the right of it An ion with a negative charge is called an anion, and has a superscript - sign to the right of it
A cation is an ion with a positive charge. Ex: Iron(III) ion, Ca2+, Mercurous ion
"Mercurous" is indeed the name of a cation, the one now most often called Hg (I).
HgO. The single mercury cation has a +2 charge, and single oxide anion a -2 charge. Mercurous oxide would be Hg2O, ie, the mecurous ion is a dimer, therefore it has two mercury atoms, each with a +1 charge. Since the oxide ion has a -2 charge , mercurous oxide is Hg2O.
thr oxidation number of mercury is + 2
A single mercurous ion has two positive charges and contains two mercury atoms and therefore has the formula Hg2+2. This cation requires two chloride anions, each which has a single negative charge, for the electroneutrality required in a compound between them, resulting in the formula given.
barium ion is a cation. rest listed are anions.
Th mercurous ion is a diatomic catiion, Hg22+, consisting of two mercury atoms covalently bonded together.

A cation is a postitve ion. Sodium (Na+) is a postitive ion. Therefore, Na+ is a cation. It's definitional.
Anion is a negative ion (Cl-) and cation is a positive ion (Na+).
The cation in the compound its Li+
A cation is a positive ion
