Iron is in group 8, period 4 of the Periodic Table. Thus, its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6 4s2. Another way to write this is [Ar] 3d6 4s2 since the beginning of the electron configuration is the same as argon's.
The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.
When an atom becomes an ion, it gains or loses electrons to achieve a full outer electron shell, resulting in a change in electron configuration. For example, a neutral sodium atom (1s2 2s2 2p6 3s1) loses one electron to become a sodium ion (1s2 2s2 2p6). The electron configuration of the ion reflects this change in the number of electrons.
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
The electron configuration of an atom with electrons in the dz2 orbital is 3d10.
The electron configuration of atomic number 26 (iron) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.

Electron configuration for an atom is the distribution of electrons on atomic orbitals.
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
The electron configuration of an atom with electrons in the dz2 orbital is 3d10.
The electron configuration of atomic number 26 (iron) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
The electron configuration of a chromium atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d5.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
The ground state electron configuration for iron (Fe) is Ar 3d6 4s2.
The ground state electron configuration of iron (Fe) is Ar 3d6 4s2.
The electron configuration of an atom with the atomic number 10 (neon) is 1s2 2s2 2p6.
