Drawing Lewis Structures with Charges

[sallina_yehdego 2E]

When drawing Lewis Structures for polyatomic molecules, what are the rules if charges exist?

[MinaChoi_3H]

For cations, remove 1 e- for each +1 charge. For anions, add 1 e- for each -1 charge.

[Sofia Ban]

It is also important to note that when counting electrons, negative ions should have extra electrons placed in their Lewis structures and positive ions should have less electrons than the uncharged molecule. After the Lewis structure of the ion is written, place the entire structure in brackets, and write the charge as a superscript on the upper right, outside of the brackets.

Can Lewis structures be used to construct the molecular structure of the element?

[Karla_Ocampo 4E]

Hi! So for drawing Lewis structures, you remove one electron for each + 1 charge, and add one electron for each -1 charge.

Can Lewis structures be used to construct the molecular structure of the element?

So Lewis Structures tell you the valence electron # of the atoms, so it can help tell you the position the atom has in a molecule. So because molecular structures are dependent on the spatial orientation of covalent bonds, drawing out the Lewis structure can help.

When it comes to actually drawing the structures, put giant brackets around the whole drawing to indicate the quantity and then mark the charge outside the brackets on the top right corner.
