What is the octet rule?

• Atoms tend to gain, lose, or share electrons to have eight electrons in their outer shell.

• Atoms always have eight protons in their nucleus.

• Atoms are stable with eight neutrons.

• Atoms form bonds to have eight bonds.

Which of the following is an exception to the octet rule?

• Helium

• Neon

• Boron

• Argon

Which molecule is an example of an exception to the octet rule?

What is the relationship between bond length and bond strength?

• Longer bonds are stronger.

• Shorter bonds are stronger.

• Bond length does not affect bond strength.

• Bond strength is always the same regardless of bond length.

Which of the following elements can have an expanded octet?

• Carbon

• Oxygen

• Phosphorus

• Hydrogen

In which of the following molecules does the central atom not follow the octet rule?

Which of the following factors does not affect bond strength?

• Bond length

• Bond order

• Electronegativity difference

• Color of the compound

Which molecule is an example of a molecule with a central atom that has less than an octet?

What is the typical bond length order for single, double, and triple bonds?

• Single > Double > Triple

• Triple > Double > Single

• Double > Single > Triple

• Single = Double = Triple

Which of the following molecules has a central atom with an expanded octet?
