Exceptions to this rule occur when:
• there is an odd number of electrons, like in radicals
• there are less than 8 electrons or incomplete octet
• there are more than 8 electrons or expanded octet. This occurs to nonmetals from Period 3 to 7.
For this problem, we need to draw the Lewis structure for each compound.
A valid Lewis structure of _____ cannot be drawn without violating the octet rule.
