Number of Lone Pairs and Bonding Pairs for BF3 (Boron trifluoride)

To determine the number of lone pairs and bonding pairs of electrons for BF3 we first need to draw as valid Lewis Structure. Once we have a Lewis Structure for BF3 then we can identify the lone and bonding pairs.

Bonding pairs of electrons are the electrons between the atoms. These form the chemical bond and are shared between atoms. Often a pair of bonding electrons is represented by a line. Each line represents a pair of bonding electrons.

Lone pairs of electrons are the remaining electrons around the atom. These are not between atoms and are not shared. The are important because they do occupy space and influence the shape of the molecule.

There are no lone pairs of electrons on the B atom in BF3 (Boron trifluoride).

We often need to know the the number of lone pairs of electrons in a molecule like BF3 (as well as electrons involved in bonds) to determine the molecular geometry, calculate formal charges, and understand polarity and chemical reactivity.

i want to ask why boron is stable at 6 electron in its valence shell it is suppose to be 8 according to octate rule or is it exception guide me please thankyou

[vengeancegaming]

Doesn't it have lone pair in second shell as it configuration is 2, 3
