What is the unit cell of calcium sulfide?

anti-fluorite
cesium cholride
diamond
fluorite
graphite
rutile
sodium chloride
zinc blende

I found a source that shows it has the NaCl structure.

thankkkkk youuuuu it was right!!!:)

To determine the unit cell of calcium sulfide, we need to consider the crystal structure of the compound. Unit cells are the repeating building blocks in a crystal lattice that describe the arrangement of atoms or ions within the crystal structure.

In the case of calcium sulfide (CaS), the crystal structure is based on the arrangement of calcium cations (Ca2+) and sulfide anions (S2-).

The correct unit cell for calcium sulfide is zinc blende structure.

The zinc blende structure consists of two interpenetrating face-centered cubic (FCC) lattices, one for calcium ions and one for sulfide ions. Each ion is surrounded by 4 ions of the opposite kind. The calcium ions occupy the tetrahedral positions, while the sulfide ions occupy the octahedral positions.

To identify the correct unit cell for a given compound, you can refer to crystal structure databases, such as the Cambridge Structural Database (CSD) or the International Crystallographic Database (ICSD). These databases provide crystallographic information on various compounds, including their unit cells and crystal structures.
