Group 1 elements are more reactive compared to Group 2 elements. This is because Group 1 elements have one electron in their outermost shell which is easily lost, making them highly reactive. On the other hand, Group 2 elements have two electrons in their outermost shell, making them less reactive as it is harder to lose two electrons compared to one.

Group 1 elements have a larger atomic radius compared to Group 2 elements. This is because the atomic radius increases down a group due to the addition of energy levels.

Group 1 elements have fewer valence electrons compared to Group 2 elements. This is because valence electrons are the electrons in the outermost shell of an atom. Group 1 elements have one valence electron, while Group 2 elements have two.

So, the correct answer is "Are more reactive".
