Rubidium sulfide is made of two ions, Rb+ and S2− . But while the individual ions may be charged, oppositely charged ions will be drafted so as the charge is neutral. The sulfide ion, S2− , thus requires 2×Rb+ for electrical neutrality.

What is the name for FeS?

Pyrrhotite, which is chemically called iron sulfide, has the ideal formula FeS (Fe = iron, S = sulfur). This formula means that in ANY AMOUNT of pyrrhotite, the ratio of iron to sulfur will be 1:1.

What is Rb+ and s2?

Rubidium sulfide | Rb2S – PubChem.

Is RB a metal or nonmetal?

rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.

What bond type is fe2o3?

It is represented by Fe2O3. The oxidation state of iron oxide is +3 and +2. The bond formed between iron and oxygen is due to the difference in electronegativity between the two atoms. Since iron is metal and oxygen is non-metal therefore the bonding between oxygen and iron is ionic.

Which compound is a molecular compound?

Molecular compounds are inorganic compounds that take the form of discrete molecules. Examples include such familiar substances as water (H2O) and carbon dioxide (CO2).

What does FeS mean in chemistry?

Ferrous sulfide (FeS)

Is FeS an element or compound?

Answer and Explanation: The chemical formula FeS stands for the compound iron(II) sulfide or ferrous sulfide. Fe is the symbol for iron (a transition metal), and S is the symbol for sulfur (a nonmetal).
