Question

How do you write/draw the Lewis structure for N?

Answer 1

Hint Lewis dot structures also known as electron dot structures. Lewis dot structures represent the valence electrons of the atoms present within the molecule. By Lewis dot structures we can visualize the bonding electrons and lone pair of electrons present in the molecule.

Complete step by step answer:
- In the question it is asked to draw the Lewis structure for N (nitrogen atom).
- Nitrogen belongs to group 15 and is present in the p-block of the periodic table.
- The atomic number of nitrogen is 7.
- Means nitrogen has 7 electrons in its electronic configuration.
- The electronic configuration of the nitrogen atom is $1{{s}^{2}}2{{s}^{2}}2{{p}^{3}}$ .
- From the above electronic configuration we can say that the nitrogen has 5 five electrons in 2s and 2p orbitals and the number of valence electrons are five in nitrogen.
- The Lewis dot structure of nitrogen atom is as follows.

 - From the above Lewis dot structure of nitrogen we can say that nitrogen has only one lone pair of electrons and three single electrons around the nitrogen atom.

Note: Without knowing the electronic configuration of the atom we cannot draw the Lewis dot structure of the atoms or elements. The three single electrons present around the nitrogen makes the nitrogen atom to form three bonds with other atoms. In all the compounds which have nitrogen atoms in its composition, nitrogen will have three bonds with other atoms.
