Chapter EH, Problem 57R

Solution

Interpretation : The noble gases have the highest first ionization energies compared to the rest of the elements on the periodic table to be analyzed.

Concept Introduction : The elements of group 18 are called a noble gas. Helium, neon, argon, krypton, xenon, and radon are among the elements of group 18.

The noble gases have the highest first ionization energies compared to the rest of the elements on the periodic table because all the noble gases have a stable electronic configuration.

The minimal amount of energy an electron in a gaseous atom or ion must absorb to escape the influence of the nucleus is known as the ionization energy.

The ionization energy usually increases along the period and decreases down the group.

The noble gases have stable electronic configurations that end with $n{s}^{2}n{p}^6$ configuration due to which they have higher ionization energy.

Noble gas has the highest first ionization energy than other elements in the periodic table.
