Sulfer is an element, only compounds can be ionic. For example, NaCl is an ionic compound- something that has a metal and a non-metal.
Sulfur as an element is neutral. As an ion it has a minus 2 charge so S2-
Calcium forms divalent cations and sulfur forms divalent anions. Therefore, the ionic compound between them is calcium sulfide, with formula CaS.
BeS- Beryllium sulphide

K2S is the formula for the ionic compound formed from potassium and sulfur.
The compounds in the system nitrogen-sulfur are not ionic.
Phosphorus has larger ionic radius than sulfur. There is more nuclear attraction in sulfur.
Sodium and sulfur together in a compound represents a ionic bonds, because sodium is a metal and sulfur is a non-metal. The chemical formula for this compound would Na2S, and its name would be sodium sulfide.
K2S is the formula for the ionic compound formed from potassium and sulfur.
K2S is the formula for the ionic compound formed from potassium and sulfur.
Sulfur trioxide is not ionic; it is covalently bonded. When dissolved in water, however, sulfur trioxide forms sulfuric acid, which is partially ionic: It dissociates into hydrogen ions and sulfate polyatomic cations.
Sulfur can form both ionic and covalent compounds. For example, sulfur dioxide is a covalent compound whereas sulfides of metals are ionic compounds.
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
