Answer

Explanation:

Step1: Analyze ionization energy

Ionization energy is the energy required to remove an electron from an atom. A lower first - ionization energy means it is easier for an atom to give up an electron. For (K), the first ionization energy is (418.8\ kJ/mol), and for (Br) it is (1140\ kJ/mol). Since (418.8<1140), (K) has a lower first ionization energy.

Step2: Analyze electronegativity

Electronegativity measures the pull of an atom on electrons in a chemical bond. (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.

Step3: Analyze atomic radius

The atomic radius of (K) is (243\ pm) and that of (Br) is (114\ pm). So (K) has a larger atomic radius than (Br).

Step4: Analyze ionic radius

The ionic radius of (K) is (152.2\ pm) and that of (Br) is (195\ pm). So their ions are not of the same size.

Answer:

(K) will give up an electron more easily than (Br).
