What should you do after summing the valence electrons from all atoms in order to draw Lewis structures?
What should you do after summing the valence electrons from all atoms in order to draw Lewis structures?
- Ignore the valence electrons and focus on the central atom octet
- Add an electron for each positive charge
- Place any leftover electrons on the central atom
- Write the symbols for the atoms and connect them with a single bond (correct)
Which type of atom is usually listed first if it has various groups bonded to it in a Lewis structure?
Which type of atom is usually listed first if it has various groups bonded to it in a Lewis structure?
- The central atom (correct)
- The atom with the highest electronegativity
- The atom with the highest number of valence electrons
- The atom with the smallest atomic radius
What happens if you have leftover electrons after completing the octets of the atoms bonded to the central atom in a Lewis structure?
What happens if you have leftover electrons after completing the octets of the atoms bonded to the central atom in a Lewis structure?
- Create additional bonds with other atoms
- Place them all on the central atom (correct)
- Distribute them evenly among all atoms
- Remove them from the structure
