Chapter 12, Problem 60E
Interpretation Introduction
Interpretation:
An explanation as to how five or six electron pairs around a central atom are possible when there are only four valence electrons from the
Concept introduction:
The number of bonds formed by an atom is generally explained by the octet rule. The octet rule states that there can be a maximum of eight valence electrons around an atom to attain stability. So, if the number of valence electrons in an atom is

The Lewis structure for SF6 is shown below. This sulfur S atom in this molecule has an expanded octet, and you are not expected to be familiar with the specific electron geometry and molecular geometry for expanded octets. Still, we can make some predictions with the knowledge that we have.
Would you predict the electron geometry and molecular geometry for SF6 to be the same or to differ? Please briefly explain your answer.
