Question

The element with highest electron affinity in the periodic table is-IodineChlorineFluorineOxygen

Toppr Admin · Accepted Answer

As an exception to the rule- Cl has higher EA as compared to F- Fluorine has very small atomic size and this makes the fluoride anion unstable due to very high charge-mass ratio- F has no d orbitals so it has small atomic size- F has EA less than that of Cl-

As an exception to the rule, Cl has higher EA as compared to F. Fluorine has very small atomic size and this makes the fluoride anion unstable due to very high charge/mass ratio. F has no d orbitals so it has small atomic size. F has EA less than that of Cl.
