It is ionic because it is between a metal and a nonmetal.
Ionic bond.
It is formed from a metal (Li) and a polyatomic anion (Cr2O7^2-), so it is IONIC.
Li2S, which is classified by the AX2 bond type. This bond type is indicative of a linear structure with 180 degree bond angles. This bond is also considered an ionic bond, forcing Lithium to become 2+ and Sulfur to be 2-.
Lithium sulfide
Lithium combines with sulphur to form lithium sulphide (Li2S)

Your instruction huh
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
