Electron Configuration Of Iron 26. The configuration of ions would be fe 3+ fe 3+ 1s 2, 2s 2 2p 6, 3s 2 3p 6 3d 5. The ground state electron configuration for a neutral atom of iron is:
The state in which all electrons have the lowest possible energy. Its symbol is short for ferrum which is a latin term. However, notice that 1s 2 2s 2 2p 6 3s 2 3p 6 is the configuration for argon, a noble gas.
