Which element is the least metallic between cadmium, silver, zinc, or iron?

Which element would mostly likely have an electron affinity measuring closest to zero

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.
