Chapter 8: Problem 16

What do we mean when we say that two ions or an atom and an ion are isoelectronic?

Short Answer

Expert verified
Two ions or an atom and an ion are isoelectronic when they possess the same number of electrons or identical electronic structure.

Step by step solution

01

Definition of Isoelectronic Species

Isoelectronic refers to two different elements (atoms or ions) possessing the same number of electrons or same electronic structure. For example, N3-, O2-, F-, Ne, and Na+ are all isoelectronic because they all have the same number of electrons (10).
02

Factors to Remember

1. Isoelectronic elements may have different atomic numbers. 2. It is important to remember that the number of protons may vary, leading to differences in atomic number. 3. In the case of ions, the element will have gained or lost electrons, to reach a stable configuration, similar to another element or ion.
