Chapter 8: Problem 24

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

Short Answer

Expert verified
Isoelectronic refers to having the same total number of electrons. For example, the Oxygen ion O2- and Neon atom Ne are isoelectronic, both having 10 electrons.

Step by step solution

01

Define Isoelectronic

Isoelectronic refers to atomic or ionic species that have the same number of electrons, regardless of their atom/ion type or the structure of these atoms or ions. It's about an equal total number of electrons.
02

Provide Examples

For instance, Oxygen (O) with an atomic number of 8 and two negative charges (O2-) has a total of 10 electrons. Similarly, Neon (Ne) which is a noble gas with an atomic number of 10 also has 10 electrons. Thus, we could say that O2- and Ne are isoelectronic because they have the same total number of electrons.
03

Summarize the concept of Isoelectronic

In conclusion, any two ions or an atom and an ion are said to be 'isoelectronic' if they have the same total number of electrons, disregarding the nature or structure of these atomic or ionic species.

Most popular questions from this chapter

Why do elements that have high ionization energies usually have more positive electron affinities?

Acidic oxides are those that react with water to produce acid solutions, whereas the reactions of basic oxides with water produce basic solutions. Nonmetallic oxides are usually acidic, whereas those of metals are basic. Predict the products of the reactions of these oxides with water: \(\mathrm{Na}_{2} \mathrm{O}, \mathrm{BaO}, \mathrm{CO}_{2}\), \(\mathrm{N}_{2} \mathrm{O}_{5}, \mathrm{P}_{4} \mathrm{O}_{10}, \mathrm{SO}_{3} .\) Write an equation for each of the reactions.

Explain why alkali metals have a greater affinity for electrons than alkaline earth metals do.

From the electron-affinity values for the alkali metals, do you think it is possible for these metals to form an anion like \(\mathrm{M}^{-},\) where \(\mathrm{M}\) represents an alkali metal?

Which of these species are isoelectronic with each other: \(\mathrm{C}, \mathrm{Cl}^{-}, \mathrm{Mn}^{2+}, \mathrm{B}^{-}, \mathrm{Ar}, \mathrm{Zn}, \mathrm{Fe}^{3+}, \mathrm{Ge}^{2+} ?\)
