Lewis dot Structure for BF4-

Some BF4-1 Characteristics

Name: Boron tetrafluoride ion
Charge: 1-
Molecular structure: Trigonal Bipyramidal

BF4-1 has 32 electrons (one more because it’s a negative ion). It forms a 3D molecule, in a trigonal bipyramidal shape. There are no lone pairs of electrons, and is quite a common ion.
BF4-1 is a molecular solid, but is a gas at room temperature.

Lewis Dot Structure for PF5

PF5
Name: Phosphorus pentafluoride
Molecular structure: trigonal bipyramidal
State at room temperature: gas
Electrons: 40

Phosphorus pentafluoride is a trigonal bipyramidal molecule. All five fluoride elements are attracted to the phosphorus element in the center, and have eight electrons in their valence shells. The phosphorus element inside has ten valence electrons.

Lewis Structure for PF5

Other names for PF5 are: phosphorus(V) fluoride, pentafluoridophosphorus, and pentafluorophosphorane

Lewis Dot Structure of N2

Nitrogen naturally exists as a diatomic molecule. The Lewis dot structuer of Nitrogen shows a triple bond, and all valence shells are satisfied. Consequently, it's extremely difficult to break apart this molecule.
