Neither, lithium nitride is ionic. It has a very unusual lattice (see link) and is a "fast ion conductor" - meaning that it does something really unusual - the ions are free to move ( a bit) and it conducts electricity.
Lithium combines with sulphur to form lithium sulphide (Li2S)
banana
it is soluble
Lithium Sulfide, formula = Li2S. It contains Li+ ans S2- ions.
Li2S
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.
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
Don't try this at home, since Li2S can react very violently with water (much like lithium or sodium metal in water).
Ionic bond.
