Question

What do you understand by isoelectronic species? Name a species that will be isoelectronic with the following atom or ion:-

Mg2+

Solution

Atoms and ions having the same number of electrons are called isoelectronic species.

Mg2+ ion has 12 – 2 = 10 electrons. Thus, the species isoelectronic with it will also have 10 electrons. Some of its isoelectronic species are F– ion (9 + 1 = 10 electrons), Ne (10 electrons), O2– ion (8 + 2 = 10 electrons), and Al3+ ion (13 – 3 = 10 electrons).

  Is there an error in this question or solution?
