Which of the following elements has the highest first ionization energy?
Element then radius (pm):
X = 105pm
Y = 175pm
Z = 274pm
I think that the answer is "Z-274pm", but I just would like to make sure.
Z wasn't correct.
Element Z has a larger radius than elements X and Y. Because the outer electrons of element Z are not attracted as tightly to the nucleus as the outer electrons of elements X and Y, we can expect element Z to have a lower first ionization energy than elements X and Y.
would it be: element X then: X=105pm?
Yes, element X has the highest IP1. The largest diameter has the lowest IP and the lowest diameter has the highest IP.
