Solution
Sodium belongs to group 1, which is the most reactive family of metals.
Calcium belongs to group 2, which is the second most reactive family of metals.
Iron is a transition metal and it is less reactive.
Neon belongs to group 18 i.e. the noble gas family. Noble gases are inert.
Therefore, the increasing order of reactivity is:
Ne < Fe < Ca < Na
