Question

Predict the electronegativity of the yet undiscovered element with Z = 119.
- I know that is kind of the same concept as figuring out the ionization energy.
- I've tried 2.4 and 2.5 but they're wrong..
PLEASE HELP!!

Answer 1

From the periodic table http://www.ptable.com/, element 119 should be in group 1. We know that the bottom left side of the table the least electronegative elements are there and the top right are the most electronegative elements there. So you'd say the electronegativity should be around 0.6 and 0.7 in between, since electronegativity of francium is 0.7

Answer 2
