# VSEPR shape of BF_{3}

## How to find the shape of boron trifluoride_{} using VSEPR theory?

Step 1: Use lewis structure guidelines to draw the lewis structure of BF_{3}.

Step2: Apply VSEPR notation, A X E

A=Number of central atoms

X=Number of surrounding atoms

E= Number of lone pairs on central atom

For the above molecule VSEPR notation will be AX_{3}E_{0}

Step 3: Use VSEPR table to find the shape.
AX_{3} has trigonal planar shape. So the shape of BF_{3} molecule is trigonal planar.
