Selected properties of antimony (Sb) and iodine (I) are listed in the table below. Element Atomic radius (pm) First ionization e
nergy (kJ/mol) Electron affinity (kJ/mol) Electronegativity Sb 145 ? –103 2.05 I 140 1008 –295 ? Which predictions can most likely be made? Sb has a lower ionization energy but a higher electronegativity than I. Sb has a higher ionization energy but a lower electronegativity than I. Sb has a lower ionization energy and a lower electronegativity than I. Sb has a higher ionization energy and a higher electronegativity than I.
a) Sb has a lower ionization energy but a higher electronegativity than I. : As per values given : Definitely Sb has lower ionization energy however the electronegativity of Sb is lower than that of iodine
b) Sb has a higher ionization energy but a lower electronegativity than I. FAlse:
Sb has lower ionization energy than I
c) Sb has a lower ionization energy and a lower electronegativity than I. True
d) Sb has a higher ionization energy and a higher electronegativity than I. False
