Re: Lone pairs

If a lone pair is a radical would it have a weaker repulsion than a complete lone pair?

I believe it's bonds, which bond has a greater angle between them, vsper, bond strengths, and shapes and structures

Get as many as you can to 0, and ensure that the center has a formal charge of 0.

Re: Polar vs covalent

Ionic bonds involve the transfer of electrons from one element to another while covalent results from the sharing.

Re: Resonance Structures

Say one way to draw the lewis structure CO2 was written as, 0-C=O(with sets electrons above the carbon and Oxygen), then the example of its resonance structure would be O=C-O. It is the rearranging or redrawing of bonds that does not change the structure itself. Please note this is not the correct l...

Re: Formal Charge and Resonance

Formal charges will give you the most stable structure, meaning you then should be able to tell based off the most stable structure if the molecule has resonance structures.
