When drawing the Lewis structure for a molecule, after drawing the skeletal structure and distributing all of the electrons around the the terminal atoms, what actions should be taken if the central atom does not have a complete octet

During the course of making Lewis structure if the central atom does not have a complete octet then the lone pair from the terminal atom is rearranged to form a double or triple bond.

Lewis structure is the representation method of bonding of atoms in a molecule along with lone pairs present in the molecules.
In this structure, valance electrons of all atoms in the molecule are distributed in such a way so that the complete octet of all atoms is obtained.

Steps to draw a Lewis structure:

First, determine the total number of valence electrons in a molecule.
Then draw the skeleton structure of the molecule with the central atom.
Draw two dots between bonded atoms.
Replace a bond pair of electrons by a single bond.
Now distribute remaining electrons in the structure to complete the valence shells of all atoms.

If the valence shell of the central atom is incompleted then rearrange or shift the lone pair of a terminal atom towards the central atom to form a double or triple bond.

So, from this, conclude that during the course of making Lewis structure if the central atom does not have a complete octet then lone pair from the terminal atom is rearranged to form a double or triple bond.
