Answer:
Noble gases: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn)
Step-by-step explanation:
The electronegativity of an element is a meassure of the affinity it has with the electrons so that the smaller the electronegativity, the smaller the affinity (closer to zero).
The elements with the smallest electronegativity are those who have completed the octet in their last level: the noble gases.
