Question

name the following ionic compound: cs2s

o a cesium ii sulfate
o b cesium sulfate
o c cesium sulfide
o d cesium ii sulfide

question 31 (2 points)
nacl (sodium chloride)

o a ionic
o b covalent

Explanation:

For \(Cs_2S\):

• Cesium (\(Cs\)) is a metal. Sulfur (\(S\)) forms the sulfide ion (\(S^{2 -}\)). In ionic compound naming, the metal (cesium) is named first, then the non - metal with its ending changed to “-ide” (sulfide). Also, cesium is in Group 1, so it has a + 1 charge and no Roman numeral is needed (since it has a fixed charge).

For \(NaCl\):

• Sodium (\(Na\)) is a metal (Group 1, forms \(Na^{+}\) ion) and chlorine (\(Cl\)) is a non - metal (forms \(Cl^{-}\) ion). Ionic compounds are formed between metals and non - metals through the transfer of electrons.

Answer:

For \(Cs_2S\): C. cesium sulfide
For \(NaCl\): A. Ionic
