Drawing Unpaired Electrons

Postby rachelle1K » Tue Nov 05, 2019 9:23 pm

If a question asks for us to find a dipole moment for a lewis structure, should we draw the unpaired electrons?

For example, in the Dino Nuggets mini supplemental questions for 2a, the answer key does not draw the unpaired electrons.

We should always draw all electrons. There aren't any lone pair electrons drawn in the answer key to 2.a) because all electrons are in bonds.

You should always account for all of the electrons in the Lewis structure. They could be as lone pairs or in bonds, but all of the electrons should be represented in the structure.

if you have lone pairs it will also affect your dipole moment, so lone pairs are important

Always draw lone pair electrons. Question 2a) did not draw them because all the electrons were properly bonded.

Yes, always include all the electrons in the structure.

Always make sure that the total number of electrons in your final Lewis dot structure (whether they be in lone pairs, bonds, or single dots in the case of the unpaired and nonbonding electrons of radicals) is equal to the sum of the valence electrons of all the atoms in the structure.

Yes always draw lone pairs in the lewis structures.
