Barium has a lower attraction for their valence electrons because there are a large number of electrons between the valence electrons and nucleus. And these electron cause great repulsion.

Explanation: Barium is present in group number 2. It is present in the last place. Its atomic number is 56. It has 2 electrons in the valence shell. There are 54 electrons between the nucleus and the valance electrons. These electrons cause repulsion to each other and the attraction of nucleus lowers for valance electrons due to long distance.
