Isoelectronic atoms/ions

[LavieTran2B]

Hello,

Can someone please explain the significance of an isoelectronic atom or ion and how it affects periodic trends?

[Meg Yuan 1G]

Isoelectronic just means that atoms and ions have the same number of electrons. For example, F 1- is isoelectronic with neon because they have the same number of electrons. However, isoelectronic atoms/ions do not have the same chemical properties, even with same number of electrons, because they have different nuclear charges.

Isoelctric atoms can have differences in all sorts of periodic trends, depending on the atom. Isoelectric just means two atoms, ions, etc share the same number of electrons.

Isoelectronic atoms are atoms/ions that have the same number of electrons and it affects periodic trends because it will change the nuclear charge between the nucleus and electrons which can affect the radius, ionization energy, and the electron affinity.

[Aanya Pramanik 1C]

Isoelectronic atoms and ions have the same number of electrons. This affects periodic trends because an ion will have a different ionization energy, radius, electron affinity, etc. than the same uncharged atom.
