SUMMARY
The discussion centers on identifying which ion is isoelectronic with the oxygen ion (O2-). The participants conclude that the sulfur ion (S2-), chlorine ion (Cl-), sodium ion (Na+), and argon (Ar) are candidates for comparison. Ultimately, it is established that the correct answer is the chloride ion (Cl-) and argon (Ar), as they share the same electron configuration of 18 electrons, while the sulfur ion does not match the oxygen ion's electron configuration.
