Formal charge (video) | Chemical bonds | Khan Academy
The formal charge of an atom in a molecule is the charge that would reside on the atom if all of the bonding electrons were shared equally.
Drawing Lewis diagrams (video) | Khan Academy
A Lewis diagram shows how the valence electrons are distributed around the atoms in a molecule. Shared pairs of electrons are drawn as lines between atoms, while lone pairs of …

Resonance (video) | Lewis Structures | Khan Academy
The whole point of resonance structures is to draw all the possible Lewis structures which can represent the same molecule. Sometimes this can be done with only two resonance …
