Understanding Lewis Dot Structures

What is the first step in drawing a Lewis Dot structure?

• Guess a structure and place the odd atom in the middle

• Calculate the total number of electrons

• Fill the outer atoms' octets

• Create bonds to complete the octet

How do you adjust the total number of electrons for a charged molecule?

• Double the charge and add to the total

• Subtract the charge from the total number of electrons

• Add the charge to the total number of electrons

• Ignore the charge

What should you do after filling the outer atoms' octets?

• Add more electrons to the outer atoms

• Recalculate the total number of electrons

• Remove electrons from the outer atoms

• Create bonds to fill the central atom's octet

In the example of ozone, what is the shape of the molecule?

• Bent

• Linear

• Tetrahedral

• Trigonal planar

What is the final step in creating a proper Lewis structure?

• Turn bonds into sticks and include lone pairs and charge

• Recalculate the total number of electrons

• Add more electrons to the central atom

• Remove excess electrons from the outer atoms
