Answer:
the correct answers is c
Explanation:
The electronegativity of bromine is 2.96 and that of potassium is less than 1, and its first ionization energy is 1139.9 kj / mol, while that of potassium is approximately 400.
Bromine has a larger first ionization energy and a greater electronegativity due to smaller atomic radius and high nuclear charge.
Bromine has a larger first ionization energy and a greater electronegativity because of smaller atomic radius and high nuclear charge. Due to the presence of more number of protons in the nucleus of bromine, more energy is required to remove the electron of outermost shell as compared to potassium which has less number of protons and large atomic radius.
The electronegativity of bromine is also higher than the potassium atom due to more high nuclear charge so we conclude that Bromine has a larger first ionization energy and a greater electronegativity.
