Question

Why are the noble gases unreactive? A They need one more electron to complete their outermost shell. B They have one electron in the outermost shell. C They don't have an outermost shell. D They have 8 electrons on their outermost shell or a complete outermost shell.

Answer 1

Noble gases are unreactive because they have a full outermost shell of electrons, providing a stable structure that doesn't readily bond with other elements.

Step-by-step explanation:

The noble gases are unreactive or inert because they have a complete outermost shell of electrons. This complete shell configuration provides a stable structure that doesn't readily bond with other elements. In the periodic table, noble gases include helium, neon, argon, krypton, xenon, and radon. Each one of these gases has a filled valence shell, which means it has achieved a stable electron configuration. Because of this, they are often used in areas where reactions are undesirable, such as inside light bulbs.
