A model of an atom of iron would include the nucleus with a set of electrons orbiting around it. Iron has 26 protons and 30 neutrons, which would be included in the nucleus. The 26 electrons of iron would be distributed into the four circular energy levels, if the Bohr model of electron configuration is used to create the model.
The Bohr model of an element's atom depicts it in a similar manner to the solar system. The nucleus has a positive charge and sits in the center of the negatively charged electrons surrounding it. In an iron atom, two electrons are located in the first and fourth energy levels in the Bohr model of iron. The second energy level contains eight electrons and the third energy level has 14 electrons.
