Verified step by step guidance1
Recall that noble gases are elements found in Group 18 of the periodic table, known for their full valence electron shells and chemical inertness.
Identify the position of each element in the periodic table: Nitrogen (N) is in Group 15, Fluorine (F) is in Group 17, Oxygen (O) is in Group 16, and Neon (Ne) is in Group 18.
Understand that the defining characteristic of noble gases is their complete outer electron shell, which makes them very stable and unreactive.
Recognize that Neon (Ne) is the only element among the options that belongs to Group 18, the noble gases.
Conclude that Neon (Ne) is classified as a noble gas because it has a full valence shell and is located in Group 18 of the periodic table.
