Answer

Explanation:

Step1: Understand ionization energy

Ionization energy is the energy required to remove an electron from an atom. Lower ionization energy means easier electron - removal.

Step2: Compare ionization energies of K and Br

K has a first - ionization energy of 418.8 kJ/mol and Br has a first - ionization energy of 1140 kJ/mol. Since K has a lower first - ionization energy, it will give up an electron more easily than Br.

Step3: Analyze electronegativity

Electronegativity measures the ability of an atom to attract electrons. Br has an electronegativity of 3.0 and K has an electronegativity of 0.82, so they do not have the same pull on electrons.

Step4: Analyze atomic and ionic radii

K has an atomic radius of 243 pm and Br has an atomic radius of 114 pm, so K is larger in size. Also, K has an ionic radius of 152.2 pm and Br has an ionic radius of 195 pm, so their ions are not of the same size.

Answer:

K will give up an electron more easily than Br.
