Lithium combines with sulphur to form lithium sulphide (Li2S)
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The ionic formula for Ca2+ and S2- is CaS, which is calcium sulfide. In this compound, calcium donates two electrons to sulfur, forming a ionic bond between the two elements.
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.
The chemical formula for lithium is Li. The chemical formula for sulfide ion is S2-. Therefore, the chemical formula for lithium sulfide would be Li2S.
The formula for the ionic compound formed from lead (Pb2+) and sulfur (S2-) ions is PbS, with a 1:1 ratio of cations to anions. Lead has a 2+ charge while sulfur has a 2- charge, so they combine in a 1:1 ratio to form a neutral compound.
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The ionic formula for Ca2+ and S2- is CaS, which is calcium sulfide. In this compound, calcium donates two electrons to sulfur, forming a ionic bond between the two elements.
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.
3S2- + 2Sc3+ --> Sc2S3name: Scandium sulfide
The chemical formula for lithium is Li. The chemical formula for sulfide ion is S2-. Therefore, the chemical formula for lithium sulfide would be Li2S.
The formula for the ionic compound formed from lead (Pb2+) and sulfur (S2-) ions is PbS, with a 1:1 ratio of cations to anions. Lead has a 2+ charge while sulfur has a 2- charge, so they combine in a 1:1 ratio to form a neutral compound.
In a chemical reaction between lithium (Li) and sulfur (S), it is likely that lithium would donate its electron to sulfur, forming an ionic bond between Li+ and S2-. This creates lithium sulfide (Li2S), an ionic compound.
The formula for the ionic compound formed between S^2- and Pb^4+ is PbS2, where lead (Pb) has a 4+ charge and sulfur (S) has a 2- charge. This results in the compound lead(IV) sulfide.
The formula for the compound formed between Li+ and S2- is Li2S. This is because lithium has a +1 charge and sulfur has a -2 charge, so two lithium ions are needed to balance the charge of one sulfur ion.
In order to form a neutral ionic compound, one K ion (with a +1 charge) would combine with two S2- ions (each with a -2 charge). Therefore, one formula unit of the compound would contain 1 K ion and 2 S2- ions.
The formula for the ionic compound formed between zinc and sulfur is ZnS, which is known as zinc sulfide. In this compound, zinc has a 2+ charge (Zn2+) and sulfur has a 2- charge (S2-), so they combine in a 1:1 ratio to form a neutral compound.
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
