What is the octet rule?
Atoms tend to gain or lose electrons to achieve a full outer shell of 8 electrons
Atoms tend to share electrons to achieve a full outer shell of 8 electrons
Atoms tend to repel each other when they have 8 electrons in their outer shell

What is the relationship between bond length and bond energy?
As bond length increases, bond energy increases
As bond length increases, bond energy decreases
As bond length decreases, bond energy increases
As bond length decreases, bond energy decreases
What is the formal charge of an atom in a molecule or ion?
