Concepts and reason A Lewis structure is a diagram that depicts the chemical bonding between atoms and represents the lone pair of electrons present on the atom. It is also called as a dot structure that represents bonding and non-bonding pairs of electrons in the molecule. A Lewis structure is used to draw covalently bonded molecules as well as coordination compounds.
Fundamentals DA Lewis structure gives an idea about the bonding and lone pairs of electrons in the molecule. Valence electrons are the

Step-by-step
FIRST STEP ALL STEPS ANSWER ONLY
Step 1 of 3 ^
(A) The valence electrons present in Nitrogen = 5 The valence electrons present in Oxygen = 6 The valence electrons present in Fluorine = 7 Therefore, total valance electrons are calculated below: 5 + 6+ 7 = 18
Explanation Hint for next step
There are three different atoms present in the NOF molecule. The valence electrons of nitrogen are five, oxygen has 6 valance electrons and fluorine has 7 valence electrons. On adding all the valence electrons, the total valence electrons are 18.
Step 2 of 3 ^
The Lewis structure of the NOF molecule is given below:

Part A The main Lewis structure of the NOF molecule is given below: Structure of NOF
Explanation Common mistakes Hint for next step The Lewis structure for the NOF molecule is depicted above and it is checked by finding the formal charges for each atom. The lone pair of electrons and bond pairs of electrons are represented on each atom of the Lewis structure.

(B) The total valence electrons present in BeF2 are calculated below: 2 +7 (2) = 16 The structure of BeF2 is given below:
Structure of BeF2
:7—
Be—
F :
From the structure of BeF2, oBeryllium forms two bonds with two fluorine atoms. Therefore, the number of bonding electrons is four. oEach fluorine atom has 6 lone pairs of electrons. Therefore, the number of non-bonding electrons is twelve.
Part B In the structure of BeF2, The number of bonding electrons = 4 The number of nonbonding electrons = 12
Explanation
The total valance electrons present in the BeF2 molecule is 16. Beryllium does not require 8 electrons to fulfill an octet configuration. Therefore, the number of bonding electrons is 4 and the number of non-bonding electrons is 12.
Answer Part A The main Lewis structure of the NOF molecule is given below: Structure of NOF
Part B In the structure of BeF2, The number of bonding electrons = 4 The number of nonbonding electrons = 12
