Li2S is a polar covalent compound because the electronegitvity of Li is 1.00 and of S is 2.5. Thus the difference is 1.5 and that makes it polar covalent.
Li2S is Lithium sulphide.
Lithium Sulfite
Lithium(II) Selenide
Lithium combines with sulphur to form lithium sulphide (Li2S)
Lithium sulfide
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
Ionic bond.
Because lithium form a cation and sulfur an anion the lithium sulfide (Li2S) form an ionic compound, a salt.

This compound is lithium sulfide - Li2S.
Li2s
Ionic bond.
Your instruction huh
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
it is soluble, as it is a polar compound that can readily mix. It will not seperate into seperate ions if that is what you mean. FYI Li2S is the exact same thing as water (H2O) except just shifted down one row on the periodic table.
