Is li2s ionic or molecular

Answer 1

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!!!!

Answer 2

Li2S is an ionic compound formed by the transfer of electrons between lithium (Li) and sulfur (S) atoms. It consists of lithium cations (Li+) and sulfide anions (S2-), which are held together by ionic bonds.

Answer 3

If you put them together, they would create Li2S. It's a binary ionic compound. Molecular compounds contain 2 nonmetals, while lithium sulfide contains a metal. If the compound contains a polyatomic, then it is a ternary compound

Answer 4

Lithium phosphate is ionic as are all lithium compounds.

Answer 5

Yes: Lithium is a metal, and nitrogen is a non-metal. Ionic compounds are comprised of a metal and a non-metal.

Answer 6

LI2SO4, lithium sulfate, is an ionic compound.

Answer 7

LiNO3 (lithium nitrate) is ionic.

Answer 8

Li2Se is an ionic compound.

Answer 9

Yes
