HW 2D #3

Is the answer BaBr2 because Ba is more of a heavier alkali metal that's placed lower in the periodic table, so it would be more ionic?

Essentially, if we go by periodic trends, Ba has the biggest electronegativity difference with Br compared to B and Be, making it the most ionic bond (ionic bond strength increases as the electronegativity difference increases between to atoms).

How do we determine the electronegativity difference without having the actual values to determine the difference?
