why is mgf2 polar?

  MgF2 is linear in the gas phase and hence nonpolar. Some heavier Group 2 halides are however bent and are polar (CaF2(g), F-Ca-F ≈ 145°)

  I don’t know what mgf2 is, but MgF2 is the insoluble salt called magnesium fluoride. It does NOT exist as a discrete molecule and is therefore, not described as “polar.” It exists as a network of Mg and F atoms. The bonds between Mg and F atoms ARE polar due to the high electronegativity difference. The bonds have over 80% ionic character.
