Answer: which chemical properties they have.
Why: Group 2 elements all have two valence electrons, so they exhibit similar chemical behavior (e.g., tend to form +2 ions, react with water/acids to give hydroxides/salts, are metallic and fairly reactive). They do not have the same total protons/neutrons or lie in the same period.
