Lewis Structure/Bonding Practice

What is the first thing you need to do when drawing Lewis Structures?

• Draw your bonds
• Count the number of valence electrons
• Subtract to make the valence number even
• Add to make the valence number even

After drawing in your bonds, what do you do if you don't have enough electrons to get each atom to its octet?

• Place dots until everything has eight
• Place dots only around the terminal atoms
• Add a multiple bond
• Have eight only around the central atom

In a Lewis structure, which element belongs in the center?

• The more positive one
• The neutral one
• The more negative one
• The largest one

Where can hydrogen be placed in a Lewis Structure?

• Only in the center
• Only on the left
• Only on the outside
• Only on the right

How many electrons do atoms need to be stable?

• 1
• 2
• 6
• 8

How many electrons does each line indicate are shared?

• 1
• 2
• 3
• 4
