Draw the main lewis structure of nof. draw nonbonding electrons using the dot notation and bonding electrons as a bond.

Answer : The Lewis-dot structure are shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.  The valence electrons are shown by 'dot'.

The given molecule is,

In this molecule, the nitrogen atom is a less electronegative element as compared to oxygen and fluorine. So, the nitrogen is the central atom and oxygen and nitrogen are the neighboring atoms.

As we know that the nitrogen has '5' valence electrons, oxygen has '6' and fluorine has '7' valence electrons.

Therefore, the total number of valence electrons in = 5 + 6 + 7 = 18

According to Lewis-dot structure, there are 6 number of bonding electrons and 12 number of non-bonding electrons.

The Lewis-dot structure are shown below.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
