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.
What else can I help you with?
How many d electrons are there in an atom of iron?
The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.
How will electron configuration of the atom change when the atom becomes an ion?
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.

Why is an iron atom a different element than a sodium atom?
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.
