D

Verified step by step guidance1
Understand the concept of the octet rule, which states that atoms are most stable when they have eight electrons in their outermost shell, also known as the valence shell.
Recognize that atoms with a full valence shell, typically containing eight electrons, are less likely to form chemical bonds because they are already in a stable, low-energy state.
Consider the noble gases, such as neon and argon, which naturally have eight electrons in their outer shell and are known for their lack of reactivity due to their full valence shells.
Identify that atoms with fewer than eight electrons in their outer shell, such as those with one, three, or four electrons, tend to form chemical bonds to achieve a stable electron configuration.
Conclude that an atom with eight electrons in its outer shell would not tend to form chemical bonds with other atoms, as it already satisfies the octet rule and is chemically inert.
