Which Of The Following Has The Smallest Radius

Which Of The Following Has The Smallest Radius – Which of the following pairs of atoms has the lowest electron affinity? a) Ca, K b) I, F c) Li, Ra. I don’t know anything serious about electronic affinity to buy another point

Electron affinity (EA) expresses how much energy a neutral atom releases when it gains an electron from a gaseous ion.

Which Of The Following Has The Smallest Radius

So, when you have to compare two factors that are in the same period, the one on the right has the higher EA. In the case of two elements from the same group, the one closer to the vertex has a higher EA.

Electron affinity is the ability to attract an electron to the outermost shell of an atom to become a 1- ion or a more negatively charged ion, e.g. 2-, etc.

The ability to do this results in nuclear charge shielding (ie more protons in the nucleus) and less filled inner shells. note These two factors lead to a smaller radius, so a smaller radius corresponds to a higher electron affinity.

That is, electron affinity increases as we go from left to right in the period (same number of shells, more protons) and decreases as we go down the group (more shells and larger radius than more protons ).

Since electron affinities are related to the formation of negative ions, it is unusual to consider them for metals. I has an electron affinity of -295 kJ/mol compared to -328 kJ/mol for F, so F has a more exothermic affinity for the first electron.
