Question

which is the name for $ce{sio_{2}}$?○ silicon dioxide○ silicon trioxygen○ disilicon dioxygen○ monosilicon oxide

Explanation:

In chemical nomenclature for covalent compounds, the first element (silicon, here with only one atom so no prefix "mono-") is named first, followed by the second element (oxygen) with a prefix indicating the number of atoms ("di-" for 2) and the suffix "-ide". This matches the formula $\text{SiO}_2$.

Answer:

silicon dioxide
