Electron Configuration Of Iron 26. The atomic number of fe (iron) is 26. The configuration of ions would be fe 3+ fe 3+ 1s 2, 2s 2 2p 6, 3s 2 3p 6 3d 5.
26 learn more about the atomic number. The expanded electron configuration is 1s22s22p63s23p63d64s2. Zinc's full electron configuration is:
Its symbol is short for ferrum which is a latin term.
So it has a valency 2. The iron sulfate is used in the fungicide. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol.
