Why do elements in the same group in the periodic table have similar properties?

because they have the same number of total electrons, which makes them react with other elements in the same way

because they have the same number of valence electrons, which makes them react with other elements in the same way

because they have the same number of core electrons, which makes them react with other elements in differents ways

because they have the same number of protons, neutrons and electrons, which makes them react with other elements in the same way
