Question

Why is Lithium more reactive than Neon? I honestly do not understand this.

Answer 1

So basically the reason why Lithium is more reactive than Neon is because, Reactivity increases for metals as you go down a group, and for nonmetals the reactivity increases as you go up on a group.

BUT AS YOU SEE, on the periodic table it seems as if Neon would have a greater reactivity, BUT the thing is that Neon is not a Metal or Nonmetal. Neon is a Noble gas and Noble gases do not have any reactivity because they have 8 valence electrons, that's why Lithium is greater in reactivity
