During an exploratory mission to an exoplanetary ring system, an automated probe analyzes four newly isolated gaseous samples of elements, designated X, Y, Z, and W, determining that all four belong to the same vertical group on the periodic table. The shipboard spectrometer records their first ionization energies as 496 kJ/mol for X, 376 kJ/mol for Y, 520 kJ/mol for Z, and 419 kJ/mol for W. Considering the fundamental periodic trends governing effective nuclear charge and electron shielding down a group, which sequence correctly ranks these elements in order of increasing atomic radius?
