The correct explanation for why noble gases are unreactive and stable is:
**They have 8 electrons in their outer shell (except for Helium).**
This is known as the octet rule, where having a full outer shell of electrons (8 for most elements, 2 for helium) makes elements more stable and less likely to react with others.
