Respuesta :
pretty sure B because they have all 8 electrons which makes it the most stable, unlike the others that arent that stable
The noble gases are already stable, with full octets of valence electrons.
What are the noble gas elements?
- A group of rare gases that include helium, neon, argon, krypton, xenon, and radon and that exhibit great stability and extremely low reaction rates due to fully filled outer orbitals.
- They are also called as inert gases.
What is meant by valence electrons?
- Valence electrons are the electrons in the outermost shell, or energy level, of an atom.
What describes the stability of fully filled outer most orbital?
- Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
- Thus, noble gases rarely form bonds with other atoms.
