Answer 1

Answer #1

Most positive : Argon > cesium > bismuth > bromine > oxygen : Most negative

Explanation

Electron affinity is the energy change when one electron is added to a neutral gaseous atom. If energy is released, then electron affinity is negative and if energy is absorbed, then electron affinity is positive.

Higher the electronegativity of element, more energy will be released upon gaining an electron.
