The outermost s and p orbitals of noble gases are completely filled, that is why the gases are _.
Correct answer: B. Stable, unreactive
- A. Stable, reactive
- B. Stable, unreactive
- C. Unstable, reactive
- D. Unstable, unreactive
Explanation
Since in noble gases, which refers to the zero group of the periodic table, all the shells are filled, as the orbitals have complete number of electrons, thus this makes these gases unreactive and stable. They are unreactive because removing electron will need a lot of energy due to highest ionization energy, and adding electron to the orbital is practically near to impossible since the shell is completely filled. Thus, Option B is correct.

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.
