Question

write the name of the following covalent compound: p₂s₃

Explanation:

Step1: Identify the elements

The compound \( P_2S_3 \) contains phosphorus (P) and sulfur (S).

Step2: Use prefixes for covalent compounds

For covalent compounds, we use prefixes to indicate the number of atoms. The prefix for 2 is "di-" and for 3 is "tri-".

Step3: Name the compound

Phosphorus is named first, then sulfur with the suffix "-ide". So we have "diphosphorus trisulfide".

Answer:

diphosphorus trisulfide
