What are the steps in drawing Lewis structures? correct answer: 1. Draw skeleton, find central atom 2. Number of valence electrons 3. 2 electrons for each pair of bonded atoms 4. Total electrons - electrons put into structure = electrons left over 5. Electrons needed to fill octets 6. Electrons needed - electrons leftover = electrons in multiple bonds How to calculate formal charge? correct answer: Formal charge = valence electrons - non-bonding electrons How do you apply ...
