What does it mean to be isoelectronic?

Answer 1

Having the same configuration of electrons

Isoelectronic particles include, for example:

18 electrons in the same numbers in the same shells make up an argon atom and a (-1) chloride ion.

Both a water molecule and a hydronium ion are examples of isoelectronic compounds; in both, the oxygen atom is surrounded by eight electrons, and hydrogen atoms are bound to this central oxygen.

Being isoelectronic means having the same number of electrons or the same electron configuration as another atom, ion, or molecule. This similarity in electronic configuration can lead to similar chemical properties among the isoelectronic species.
