A nitrogen trifluoride molecule contains numerous lone
pairs. Draw its Lewis structure.

A structure where valence electrons are denoted by dots around the atomic symbol of an atom is called a Lewis dot structure or Lewis structure.

Chemical formula of nitrogen trifluoride is $N{F}_{3}$

Atomic number of nitrogen is 7 and its electronic distribution is 2, 5. So, it has 5 valence electrons.

Atomic number of fluorine is 9 and its electronic distribution is 2, 7. So, it has 7 valence electrons.

Therefore, total number of valence electrons present in $N{F}_{3}$ are as follows.

Hence, there are 26 valence electrons present for bonding. And, there are 2 electrons present in a pair.

Therefore, total pair of valence electrons are present as follows.

Hence, the Lewis structure of $N{F}_{3}$ is as follows.

So, there are 3 electron pairs utilized in bonding and 10 electron pairs are remaining. Each F-atom has 3 lone pair of electrons and N-atom has one lone pair of electrons.

Answer: Lewis structure of nitrogen trifluoride is as follows.
