BeF2 Beryllium Difluoride:

First draw the Lewis dot structure:
BeF2 Lewis Structure
Electron geometry: linear. Hybridization: sp

Then draw the 3D molecular structure using VSEPR rules:
Click and drag the molecle to rotate it.

The molecular geometry of BeF2 is linear with symmetric charge distribution on the central atom.
Therefore BeF2 is nonpolar.
