The properties of two elements are listed below. element atomic radius (pm) ionic radius (pm) first ionization energy (kj/mol) electron affinity (kj/mol) electronegativity br 114 195 1140 –325 3.0 k 243 152.2 418.8 –48.4 0.82 which prediction is supported by the information in the table? k will give up an electron more easily than br. both k and br will have the same pull on electrons. k will have a smaller size in comparison to br. both k and br will produce ions of the same size.

Based on the data presented in the table and comparing it to the given statements we can interpret that potassium (k) will give up electrons readily than bromine (Br)

Now, ionization energy is the amount of energy required to remove an electron from an atom or ion. In the case of K the first IE = 418.8 kJ/mol while for Br, IE = 1140 kj/mol. Thus the ionization energy of Br >> K which supports the prediction that K will give up an electron more easily than Br.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
