What is the geometry name for PF5? Is PF5 polar or non-polar?

Magnesium has 12 electrons arranged in three energy levels. The outer level has two electrons. In order to become stable, the atom loses two electrons thus exposing the previous level with 8 electrons and subsequently becomes an ion withA.
