Which of these molecules is least likely to exist: NF5, PF5, SbF5, or IF5? Explain why.
The most common exceptions to the octet rule are compounds or ions with central atoms having more than eight electrons around them. PF5, SF4, CIF3, and Br3 are examples of this type of exception. Draw the Lewis structure for these compounds or ions. Which elements, when they have to, can have more than eight electrons around them? How is this rationalized?
