What is 'li2s' .?
If you mean 'Li2S'. Then it is an ionic molecule.
Lithium atom form the lithium ion.
Li(s) = Li^(+) + e^-
Sulphur has electron affinity and forms the sulphide ion.
S(s) + 2e^(-) = S^(2-)
Since these two ions have opposite charge (+/-), they are attracted to each other like the North and South poles of a magnet.
Also the charges must balance . So you need 2 lithium ions (2Li^(+)) to give an overall positive charge of '2+'. to balance with the '2-' of the sulphide ion.
The two lithium ions are electrostatically attracted to the sulphide ion to form the molecule lithium sulphide.
Overall it is described as an ionic molecule.
The balanced equation is
2Li(+) + S^(2-) = Li2S.
NB . When writing chemical formula, a one letter symbol is ALWAYS a CAPITAL letter. A two letter symbol is ; first letter is a CAPITAL letter and the second letter is always small/lower. case.
So sulphur is 'S' not 's' and lithium is 'Li' not 'li'.
Hope that helps!!!!
The name of the ionic compound Li2S is lithium sulfide.
The name of the ionic compound Li2S is lithium sulfide.
Li2S has an ionic bond. Lithium (Li) is a metal that donates an electron to sulfur (S), a non-metal, resulting in the formation of an ionic compound where Li becomes Li+ and S becomes S2- to form an ionic bond.
Lithium combines with sulphur to form lithium sulphide (Li2S)
It is formed from a metal (Li) and a polyatomic anion (Cr2O7^2-), so it is IONIC.
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.

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.
