What does isoelectronic mean? It was #5D on the midterm. The question asked to choose the two ions that were not isoelectronic with fluoride ion (F-). I answered correctly with the ions O- and N2- but I do not fully understand the concept.

Isoelectronic means that the two ions have the same number of valence electrons.

F^- has valence 8 electrons
Because O^- and N^2- each have only 7 valence electrons, they are not isoelectronic with F^-

Isoelectronic means that both atoms have the same number of valence electrons. Ex: Na+,F-

Isoelectronic means that both atoms have the same number of valence electrons. Ex: Na+,F-

Isoelectronic means that the two atoms have the same number of valence electrons

Isoelectric is referring to an element that has the same amount of valence electrons.

Isoelectronic means the atoms have the same number of valence electrons! hope this helps

isoelectronic: having the same numbers of electrons or the same electronic structure.

Isoelectronic means that two ions/an ion and an element have the same amount of valence electrons

Isoelectric means 2 atoms that share the same electron configuration of the outermost shell (share the same number of valence electrons)

Isolelectronic means that two atoms have the same number of valence electrons and the same electron configuration

Can elements only be isoelectronic if they have the same # of valence electrons?

Isoelectronic means 2 different elements have the same number of valence electron.

Isoelectric means that two atoms have the same number of valence electrons. F- would have 8 valence electrons. O- would have 7 valence electrons. N2- would have 7 valence electrons. Therefore these two atoms are not isoelectronic to F- as they both have one less valence electron.

How does being isoelectric affect polarizability?
