Recall that noble gases are elements found in Group 18 of the periodic table, characterized by their full valence electron shells, making them very stable and mostly inert.
Identify the group or family of each element listed: Nickel (Ni) is a transition metal, Nitrogen (N) is a nonmetal in Group 15, Neon (Ne) is in Group 18, and Sodium (Na) is an alkali metal in Group 1.
Recognize that the noble gases include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Since Neon (Ne) is the only element listed that belongs to Group 18, it is classified as a noble gas.
Therefore, the correct classification is Neon (Ne) as a noble gas based on its position in the periodic table and its chemical properties.
