Lithium is cation, because it is positivelycharged. Whenever a single element is positive , like calcium, it will be cation.While oxygen, which is negatively charged, will be anion.
They are compounds which have a cation made up of a metal and sulfide ion as the anion.
Because lithium form a cation and sulfur an anion the lithium sulfide (Li2S) form an ionic compound, a salt.
Here the anion is S2-.
A lithium cation with formula Li+1.
Lithium form the cation Li2+.
Mercury(II) Sulfide. Made of Mercury cation and Sulfide anion.

Because lithium form a cation and sulfur an anion the lithium sulfide (Li2S) form an ionic compound, a salt.
Copper is the cation (+) and sulfur the anion (-).
A lithium cation with formula Li+1.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
Elemental lithium (Li) is neither a cation nor an anion. But when Li loses it's one valence electron, it will become a CATION (Li^+).
Lithium. Lithium and hydrogen combine to make lithium hydride, an ionic compound, in which lithium is the cation (positive) and hydrogen is the anion (negative). The cation is always first in the chemical formula for an ionic compound.
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
