2.4B: Isoelectronic Molecules – Chemistry LibreTexts
16 janv. 2023Isoelectronic matricies–all isoelectronic species in a matrix defined by total electrons and valence electrons vary by progression in group number. For example, a 14 electron/10 valence electron diatomic matrix would have molecules such as CN -, CO, and N 2. Isoelectronic arrays–an atom is replaced with another which alters the charge and …
6.5: Periodic Variations in Element Properties
Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N 3-, O 2-, F -, Ne, Na +, Mg 2 +, and Al 3 + (1s 2 2s 2 2p 6). Another isoelectronic series is P 3-, S 2-, Cl -, Ar, K +, Ca 2 +, and Sc 3 + ([Ne]3s 2 3p 6). For atoms or ions that are isoelectronic, the …

Isoelectronic Definition – Chemistry Glossary – ThoughtCo
Isoelectronic refers to two atoms, ions, or molecules that have the same electronic structure and the same number of valence electrons.The term means equal electric or equal charge. Isoelectronic chemical species typically display similar chemical properties. Atoms or ions with the same electronic configurations are said to be to each other or to have the same isoelectronicity.

4.5 Ionic Radii and Isoelectronic Series – Chemistry Fundamentals
Such a set of species is known as an isoelectronic series. For example, the isoelectronic series of species with the neon closed-shell configuration (1s 2 2s 2 2p 6) is shown in Table 4.5.2. The sizes of the ions in this series decrease smoothly from [latex]ce{N^3-}[/latex] to [latex]ce{Al^3+}[/latex].

Isoelectronic Species: Definition, Examples
19 août 2023An isoelectronic series is formed by atoms, ions, or molecules that have an equal number of electrons. Examples of an isoelectronic series include nitrogen (N 2 ), carbon monoxide (CO), and oxygen cation (O+). O 2−, F −, Na +, Mg 2+, and Al 3+ all have different numbers of electrons. Another example.

Isoelectronicity – Wikipedia
Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are , while CH 3 COCH 3 and CH 3 N = NCH 3 are not.. This definition is sometimes termed valence …

Isoelectronic series: a fundamental periodic property
This author defines an isoelectronic matrix as one in which all species are isoelectronic and the variation along each axis is provided by a progression in Group number. As an example, there is an isoelectronic matrix of 14/10-electron diatomic species, where 14 is the total number of electrons and 10 the number of valence electrons.
