Based on their positions in the periodic table, which of the following elements would you expect to have the highest electronegativity value?
astatine (At) barium (Ba) chlorine (Cl) magnesium (Mg)

Respuesta :

Chlorine (Cl) has highest electronegativity. 
It is closest to the upper right angle of the Periodic table, where nob-metals are located.
All other elements that we see here in reality have more or less strong metalic properties.
