Drawing Lewis Structures Basics

Play an AI-generated podcast conversation about this lesson

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?

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?

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

If there are not enough electrons to give the central atom an octet in a Lewis structure, what should you try?
