Question

which of the following be the correct lewis structure for cacl₂? a.
:cl:−ca−:cl:
m.
:cl: = ca = :cl:
g.
:cl:⁻ ca²⁺ :cl:⁻

Explanation:

Step1: Identify bond type

$\text{CaCl}_2$ is ionic (metal + nonmetal).

Step2: Determine ion charges

Calcium forms $\text{Ca}^{2+}$; chlorine forms $\text{Cl}^-$.

Step3: Match to Lewis structure

Ionic Lewis structures show separate ions with charges, so the structure has $\text{Ca}^{2+}$ between two $[:\ddot{\text{Cl}}:]^-$.

Answer:

C. $[:\ddot{\text{Cl}}:]^- \text{Ca}^{2+} [: \ddot{\text{Cl}}:]^-$
