To determine the electron configuration of an element, such as iron (Fe), you can use the periodic table as a reference.

1. Locate the element iron (Fe) on the periodic table. It is found in the 4th row (period) and belongs to group 8, which is also known as the transitional metals.

2. The atomic number of iron is 26, indicating that it has 26 electrons. Electrons fill up atomic orbitals following a specific pattern known as the "Aufbau principle."

3. The Aufbau principle states that electrons occupy the lowest energy levels first before moving to higher ones. So, let's go through the electron configuration of iron step by step:

- The first two electrons fill the 1s orbital.
- The next two electrons occupy the 2s orbital.
- The following six electrons go into the 2p orbital.
- The subsequent two electrons fill the 3s orbital.
- The next six electrons occupy the 3p orbital.
- The next ten electrons fill the 3d orbital.
- Finally, the remaining two electrons go into the 4s orbital.

4. Summing up all these electron distributions, we get the electron configuration of iron (Fe):

1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶ 4s²

Hence, the electron configuration of iron (Fe) is: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶ 4s².
