Question

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

Explanation:

The compound Cs₂O consists of two cesium (Cs) atoms and one oxygen (O) atom. In naming binary ionic compounds, we state the metal first (cesium) and then the non - metal with its ending changed to 'ide'. Since there are two cesium atoms, the prefix 'di -' is used for the metal when naming. So it is called dicesium monoxide.

Answer:

dicesium monoxide
