B) diamagnetic.
C) ferromagnetic.
D) lanthanides.
E) isoelectronic.

Question

Quizplus · Accepted Answer

Xenon atoms, iodide ions (I-), and cesium ions (Cs+) are isoelectronic, meaning they all have the same number of electrons. Xenon has 54 electrons, iodide ions gain one electron to have a total of 54 electrons, and cesium ions lose one electron to also have 54 electrons.
