Question

what is the name of this compound? cs2o
cesium monoxide
cesium oxide
not a compound
cesium oixide

Explanation:

The compound Cs₂O consists of two cesium (Cs) atoms and one oxygen (O) atom. In naming binary ionic compounds where the metal (cesium here) has a fixed - charge, we name the metal first followed by the non - metal with its ending changed to 'ide'. Cesium is the metal and oxygen becomes oxide. So the name is cesium oxide.

Answer:

cesium oxide
