Question

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

Explanation:

The chemical formula Cs₂O indicates that there are two cesium (Cs) atoms and one oxygen (O) atom. In naming binary ionic compounds, the metal (cesium here) is named first followed by the non - metal (oxygen), with the non - metal ending in 'ide'. Since there are two cesium atoms, the prefix 'di -' is used for the metal in the name.

Answer:

dicesium oxide
