Answer

Answer:

A. K will give up an electron more easily than Br.

Explanation:

Step1: Analyze ionization energy

First - ionization energy of K is 418.8 kJ/mol and of Br is 1140 kJ/mol. Lower ionization energy means easier to remove an electron. Since K has a lower first - ionization energy, it gives up an electron more easily.

Step2: Analyze electronegativity

Electronegativity of K is 0.82 and of Br is 3.0. Higher electronegativity means more pull on electrons. Br has a higher electronegativity, so they don't have the same pull on electrons.

Step3: Analyze atomic radius

Atomic radius of K is 243 pm and of Br is 114 pm. K has a larger atomic radius, not smaller.

Step4: Analyze ionic radius

Ionic radius of K is 152.2 pm and of Br is 195 pm. They do not produce ions of the same size.
