Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical-radical combination reaction is the formation of a new electron-pair bond. write lewis formulas for the reactant and product species in the following chemical equation. include nonbonding electrons.

n(g)+no(g) = nno(g)

The Lewis formula is structural representation that indicates the bonding between atom of a molecule by line and dots used to indicates the electron position around the atoms, electron pair is known as lone pair of electrons shown by pair of dots. The electrons indicated in the structure are valence electrons.

The given atoms are and .

, whose atomic number is 7.

Electronic configuration for is .

Number of valence shell electrons for is 5.

, whose atomic number is 8.

Electronic configuration for is .

Number of valence shell electrons for is 6.

The Lewis formula for  and is shown in the image.

The atoms combine to form molecule in order to complete their octet that is to get 8 electrons in their valence shell and get stabilize in nature.

The total number of valence shell electrons in is:

The distribution of electrons in the atom will take place in such a way that formation of triple bond will take place between two nitrogen atoms and a single bond will form between nitrogen and oxygen atom. In order to complete their octet, the nitrogen atom in center will possess 1+ formal charge and oxygen will possess 1- charge (oxygen is  electronegative atom). Thus, results in formation of neutral molecule.

The formal charge on each atom is calculated using:

The Lewis formula of is shown in the image.

i do not get it   at all
