Question

What makes the Noble Gases the least reactive elements on the periodic table?

Answer 1

The answer is the letter C

Answer 2

Answer:

C

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds. The noble gases are the least reactive of any elements on the periodic table.All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are also called inert gases because they do not react with other elements of periodic table. The reason behind their inertness is that their outermost shell is complete and they do not have the tendency to lose or gain electrons.
