If two or more species have the same number of electrons, resulting in similar lewis structures, they are said to be ____.
a. covalent
b. isoelectronic
c. ionic
d. neutral
e. resonant structures

Respuesta :

Isoelectronic molecules or ions are those that have the same amount of electrons and the same Lewis structure.

As a result, the correct answer is (b) isoelectronic.

What is isoelectronic, and what are some examples?

  • When two atoms, ions, or molecules share the same electronic structure and valence electron count, they are said to be isoelectronic.  
  • Chemically, isoelectronic species frequently share comparable traits. It is referred to as having the same isoelectronicity or being isoelectronic to other atoms or ions with the same electronic configurations.

Examples of Isoelectronic:

  • The Ca2+ ion and the K+ ion share an isoelectronic bond. Nitrogen gas (N2) and NO+ have isoelectronic bonds with the carbon monoxide (CO) molecule. To CH2=N=N, CH2=C=O is isoelectronic.
  • With 10 electrons, O2-, F-, and Mg2+.
