Question

Which elements from the periodic table are the least reactive

Answer 1

Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:

(The Option in Bold is Correct)

• O the group with fluorine at the top

• O the group with carbon at the top

• O the group with helium at the top

• O the group with hydrogen at the top

Answer 2

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.
