Question

Which statement best explains why radon and Krypton do not bond easily with other elements.

a. They have many electron shells, so their protons do not attract electrons strongly.
b. They have eight electrons in their valence shells, so they are stable without gaining or losing electrons.
C. Their valence shells are empty, so they don't need to bond with other elements to be more stable

Answer 1

b is right. i checked for it

Answer 2

b. They have eight electrons in their valence shells, so they are stable without gaining or losing electrons.

Step-by-step explanation:

As all noble gases, which are located on the far right extreme of the periodic table, they all have exactly 8 valence electrons on their valence shell, this means that they are stable without wining or losing electrons, so they do not need to bond with other elements.
