Question

electron affinity A neutral atom of the element in a gaseous state. A more negative electron become more negative going from left to right across a row in the table and les smoothly periodic as some of the other properties, with some major exceptions group 18 elements have positive electron affinities, and each of the row 2 them in the column In general, however, electron affinities tend to be more Which element has the highest (most negative) electron affinity? Electronegativity is another periodic property An atoms electronegativity describes chemical compound Electronegativity increases diagonally from the lower left to the elements nonmetals whereas elements metals

Explanation / Answer

F has highest electron affinity.   as it gets octate if it gains one electron

remaining elements cant gain electrons. Xe is completely and remaining are metals so they donot accept the electrons readyly,
