Final answer:
The dot structure of BeCl2 is a linear structure with a bond angle of 180°.
Step-by-step explanation:
The Lewis structure of BeCl2 shows two electron pairs around the central beryllium atom. With two bonds and no lone pairs of electrons on the central atom, the bonds are as far apart as possible, which results in a linear structure. The bond angle is 180°, and the dot structure can be represented as follows:
Be — Cl — Cl
