Verified step by step guidance

Understand the concept of electron shells: Atoms have electron shells that surround the nucleus, and these shells can hold a certain number of electrons.

Learn about the octet rule: Atoms tend to be most stable when their outer shell is filled with eight electrons, which is known as the octet rule.

Recognize that atoms with a full outer shell do not need to form bonds: When an atom has eight electrons in its outer shell, it is considered stable and does not need to form chemical bonds with other atoms.

Identify the exception to the octet rule: While the octet rule is a general guideline, there are exceptions, such as hydrogen and helium, which are stable with two electrons in their outer shell.

Apply this knowledge to the problem: An atom with eight electrons in its outer shell is unlikely to form chemical bonds because it is already stable according to the octet rule.
