What does it mean to have a element that is isoelectronic? One of my practice questions asks me to "identify the neutral element that is isoelectronic with the cation Po^4+". I'm totally stumped.

"What does it mean to have a element that is isoelectronic? One of my

isoelectronic with the cation Po^4+". I'm totally stumped."

Isoelectronic means that the neutral element and cation have the same
electron configuration. For instance, Na+ has is isoelectronic with the
element Neon, because when Na looses one electron (and becomes Na+) it takes
on the electronic configuration of the element that normally has one less
electron. Remember, Na has 11 electrons, and Ne has 10. Na+ has 10
electrons.

Po 4+ will be four less than Po on the periodic table in terms of electron
number.

Hope this helps,
Mike KL5
