Why do you need two sodium ions for every sulfide ion in sodium sulfide?
In sodium sulfide (Na2S), two sodium ions are needed for every sulfide ion to balance the charges. Sodium has a +1 charge, and sulfide has a -2 charge. By having two sodium ions (each with a +1 charge) for every sulfide ion (with a -2 charge), the overall compound achieves charge neutrality.
How many potassium ions are needed to balance the charge of one sulfide ion and why?
You would need two potassium ions to balance the charge of one sulfide ion. Potassium has a charge of +1, while sulfide has a charge of -2, so two potassium ions with a total charge of +2 would balance the charge of one sulfide ion with a charge of -2.
How many K and S2- ions would be in formula unit of the ionic compound formed by these ions?
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.
Formula of ionic compounds made with the following ions sodium and sulfide ions?
The formula of the ionic compound composed of sodium and sulfide ions is Na2S. This is because the charges of sodium and sulfide ions are +1 and -2 respectively, so two sodium ions are needed to balance the charge of one sulfide ion.
Which substance has a chemical formula with the same ratio of metal ions to nonmetal ions as in potassium sulfide?
lithium, sodium, caesium, rubidium sulphides: Me2S.
How many lead ions surround each sulfide ion?

How many lead ions would surround each suflide ion?
In a typical lead sulfide (PbS) crystal structure, each sulfide ion (S²⁻) is surrounded by four lead ions (Pb²⁺) in a tetrahedral arrangement. Conversely, each lead ion is coordinated by four sulfide ions. This arrangement reflects the ionic bonding and geometric preferences in the PbS lattice.
If the pattern of ions shown here for galena is expanded in every directionhow many sulfide ions would surround each lead ion?
Each lead ion would be surrounded by six sulfide ions in a cubic closest packing arrangement, which is the most efficient way for spheres to pack together. In this arrangement, each sphere is surrounded by six other spheres.
How many sulfide ions would surround each lead ion?

If the pattern of ions shown here for galena is expanded in every direction how many sulfide ions would sorround each lead ion?
In galena (PbS), the structure consists of lead ions (Pb²⁺) surrounded by sulfide ions (S²⁻). Each lead ion is coordinated by four sulfide ions in a tetrahedral geometry. Therefore, if the pattern is expanded in every direction, each lead ion will still be surrounded by four sulfide ions.
How many sulfide ions surrounds the each lead ion?
In lead (II) sulfide (PbS), each lead ion is surrounded by six sulfide ions in a octahedral arrangement.
How would the hydroxide ions influence the concentration of sulfide ions?
Hydroxide ions can form insoluble compounds with sulfide ions, leading to the precipitation of metal sulfides. This would reduce the concentration of sulfide ions in solution by removing them from the aqueous phase.
Why are there more sodium ions in the sulfide compound?
In a sulfide compound, sodium ions are present to balance the charge of the sulfide ions. Sulfide ions (S²⁻) carry a -2 charge, meaning two sodium ions (Na⁺), each with a +1 charge, are needed to achieve charge neutrality. Thus, for every sulfide ion, there are typically two sodium ions in the compound, resulting in a higher number of sodium ions relative to sulfide ions.
How many sulfur ions are joined to each zinc ions in the compound zinc sulfide?
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
What does the formula of sodium sulfide mean?
The formula of sodium sulfide, Na2S, indicates that each sodium sulfide molecule contains two sodium (Na) ions and one sulfide (S) ion. The ratio of sodium ions to sulfide ions in sodium sulfide is 2:1.
If the pattern of ions for galena is expanded in every direction how many ions would surroundeach lead ions?
In galena (PbS), the crystal structure forms a face-centered cubic lattice. Each lead ion (Pb²⁺) is surrounded by six sulfide ions (S²⁻) in an octahedral arrangement. When expanding this pattern in all directions, each lead ion remains coordinated to six surrounding sulfide ions, maintaining this octahedral geometry throughout the structure. Thus, each lead ion is consistently surrounded by six sulfide ions in the expanded lattice.
Why do you need two sodium ions for every sulfide ion in sodium sulfide?
In sodium sulfide (Na2S), two sodium ions are needed for every sulfide ion to balance the charges. Sodium has a +1 charge, and sulfide has a -2 charge. By having two sodium ions (each with a +1 charge) for every sulfide ion (with a -2 charge), the overall compound achieves charge neutrality.
