The properties of two elements are listed below. element atomic radius (pm) ionic radius (pm) first ionization energy (kj/mol) electron affinity (kj/mol) electronegativity br 114 195 1140 –325 3.0 k 243 152.2 418.8 –48.4 0.82 which prediction is supported by the information in the table?

These were the choices I found on the internet:
K will give up an electron more easily than Br.
Both K and Br will have the same pull on electrons.
K will have a smaller size in comparison to Br.
Both K and Br will produce ions of the same size.

The answer is A - K will give up an electron more easily than Br.

Electron affinity value indicates the like hood that an element will accept an electron. In this case, Br electron affinity is greater than the electron affinity of K.
