And in this problem, using noble gas notation, nosotros have to write the electron configuration of iron three irons now iron. It has atomic number 26 bespeak, and so the neutral atomic number 26 atom has 26 protons and 26 electrons, so its electron configuration volition be hither is argon. It ends with iii south: 23 p. 6. And then there will be 4 southward 2. And then here eighteen electrons and here 2 electrons 20. And so it volition exist 3 d, 6, full, 26 electrons and when neutral iron loses 3 electrons it produces fe 3 ion a p 3 plus iron point. Then 3 plus means lost 3 electrons and that will be from the outer valence electrons. So here, two electrons will be gone and 1 electron will be gone from 3 d. Sub sells so electron configuration of a f 3 plus ion volition be argon. 3 d, 5.
