Atoms or ions that have the same electron configurations are:
A) paramagnetic.
B) diamagnetic.
C) ferromagnetic.
D) lanthanides.
E) isoelectronic.

Question

Quizplus · Accepted Answer

Atoms or ions that have the same electron configurations are said to be isoelectronic. This means that they have the same number of electrons and occupy the same electron orbitals. Therefore, they have similar chemical and physical properties. Choice A (paramagnetic) and C (ferromagnetic) refer to the magnetic properties of materials, and choice B (diamagnetic) describes materials that are not magnetic. Lanthanides (choice D) are a series of elements found in the f-block of the periodic table and are characterized by the filling of 4f orbitals. This concept is unrelated to the electron configurations of atoms or ions.
