The outermost s and p orbitals of Noble gases are completely filled that why they are:
Correct answer: B. stable, unreactive
- A. stable, reactive
- B. stable, unreactive
- C. unstable, reactive
- D. unstable ,uncreative
Explanation
Noble gases are gases which are completely filled valence shell. Since He has only s-orbital, its outermost shell is completely filled and hence it is stable. Other noble gases have an outer shell as p-orbital electrons along with s-orbital. So there are 8 electrons in the outermost orbital and hence it is completely filled and is stable. Hence valence shell of noble gases contains 2 electrons in case of He and 8 electrons in case of other noble gas.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
