How do you draw a Lewis structure?

When you draw a lewis structure you have to pay special attention to the valence electrons in each atom; they help determine if there are single/double/triple bonds. There is normally a center atom, and that is normally the atom that has the lowest ionization energy. For bonds (when the molecule is neutral) you arrange them according their valence electrons. This is easier if you find the total number of valence electrons first and then arrange the lewis structure.

To draw a Lewis structure, you first look at the amount of electrons you have from the elements on the periodic table. Depending on how many elements you have, draw bonds between the elements first and confirm how many electrons are used in the bond. Afterwards, use the remaining electrons to draw in lone pairs and if you don’t have enough, use double or triple bonds.

Does this also have to deal with a structure being the most stable structure or is that something else...?

You begin to find the most stable structure when you notice that there is resonance (multiple ways to draw the structure), resonance will indicate that the sructure is more stable and the real structure would be a hybrid/average of all the possible structures. The best representation of a structure can be found through formal charges (the most stable being when FC=0).

Typically the structure with the most charges on the atoms closest to zero is the more stable lewis structure. Hope this makes sense!
