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.

Potassium sulfide
sodium and sulfide
Formula for potassium sulfide is K2S.
The chemical name for Na2S is sodium sulfide. It is composed of two sodium (Na) ions and one sulfide (S) ion. Sodium sulfide is commonly used in industries such as paper production and water treatment.
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.

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.
Each lead ion would be surrounded by six sulfide ions. This arrangement is based on the coordination number of lead, which is typically 6 in the formation of lead sulfide (PbS) crystal lattice.
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.
