Which statements concerning potassium and bromine are true?

A) Bromine has a smaller atomic radius and smaller first ionization energy.
B) Bromine has a larger atomic radius and larger first ionization energy.
C) Bromine has a larger first ionization energy and a greater electronegativity.
D) Potassium has a smaller atomic radius and less electronegativity.

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.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
