Question

review the periodic table to answer this question. which of the following molecules would be considered a molecular compound?
cucl₂
o
k₂s₃
cs₂

Explanation:

Step1: Recall molecular compound definition

Molecular compounds are formed by non - metals sharing electrons.

Step2: Analyze each option

• $\text{CuCl}_2$: Copper ($\text{Cu}$) is a metal, so it forms an ionic compound, not a molecular one.
• $\text{O}$ is just an atom, not a compound.
• $\text{K}_2\text{S}_3$: Potassium ($\text{K}$) is a metal, forms an ionic compound.
• $\text{CS}_2$: Carbon ($\text{C}$) and sulfur ($\text{S}$) are non - metals. They share electrons to form a molecular compound.

Answer:

$\text{CS}_2$
