The elements found in group 2a, from top to bottom, include beryllium, magnesium, calcium, strontium, and barium. which of these elements has the highest electronegativity value? beryllium magnesium calcium barium

The correct answer is Beryllium. They all belong to atoms that have low electronegativity, and as you go down the group the farther away you are the lower it gets. This means that they are not good at bonding with and attracting pairs of electrons. Berryllium has an electronegativity of 1.5, which is low compared to Fluorine, the highest one that has 4.
