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 and adding the remaining electrons, what do you do if you don't have enough electrons to get each atom to its octet?

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

In a Lewis structure, what do you do  with the total number of valence if your ion is 2- charged?

• Add 2 to the valence number
• Subtract 2 from the valence number
• Multiply the valence number by 2
• Divide the valence number by 2

In a Lewis structure, what do you do  with the total number of valence if your ion is + charged?

• Divide the valence number by 1
• Multiply the valence number by 1
• Add 1 to the valence number
• Subtract 1 from the valence number

Where can hydrogen be placed in a Lewis Structure?

• Only in the center
• Only on the left
• Only as a terminal atom
• Only on the right
