Verified step by step guidance
1
Understand that the reactivity of elements depends on their position in the periodic table, particularly their group (column).
Recall that the least reactive group of elements is the noble gases, which are located in Group 18 of the periodic table.
Identify the elements given: Na (Sodium) is an alkali metal in Group 1, Fe (Iron) is a transition metal, Cl (Chlorine) is a halogen in Group 17, and Ne (Neon) is a noble gas in Group 18.
Recognize that noble gases have a full valence shell, making them very stable and the least reactive elements.
Conclude that among the options, Ne (Neon) belongs to the least reactive group of elements on the periodic table.
