Qual è la configurazione elettronica dello ione ferro iii?

Risposta:

The configurazione elettronica for the iron(III) ion is:

"1s"^2"s"^2"2p"^6"3s"^2"3p"^6"3d"^5"

Spiegazione:

The element iron, Fe, has the numero atomico 26, which is the number of protons in its atomic nuclei. A neutral iron atom has 26 protons and 26 electrons. In order to form a 3^+ ion, it must lose three electrons.

The ground state electron configuration for a neutral atom of iron is:

"1s"^2"s"^2"2p"^6"3s"^2"3p"^6"3d"^6"4s"^2"

The electron configuration for the iron(III) ion is:

"1s"^2"s"^2"2p"^6"3s"^2"3p"^6"3d"^5"

The Fe atom loses two "4s" elettroni e uno "3d" elettrone.
