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.
The name of the ionic compound Li2S is lithium sulfide.
The name of the ionic compound Li2S is lithium sulfide.
Lithium combines with sulphur to form lithium sulphide (Li2S)
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
Lithium sulfide (Li2S) is an ionic bond. It forms between lithium, which donates an electron to become a positive ion, and sulfur, which accepts the electron to become a negative ion. This electrostatic attraction between the oppositely charged ions holds the compound together.

Li2s
This compound is lithium sulfide - 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.
Your instruction huh

When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
The oxidation number for sulfur in Li2S is -2. In lithium sulfide (Li2S), each lithium atom has an oxidation number of +1, and since the compound is neutral overall, the total oxidation number for sulfur must be -2 to balance the charges.
