Iron has several isotopes but the most common is Fe56. which is 92 percent of natural Iron, so I will describe that.
This has a nucleus with 26 protons and 30 neutrons. It therefore has 26 electrons and the electron shells contain 2, 8, 14, and 2 electrons (from inner to outer shells).
So color your protons and neutrons differently and stick 26 and 30 of these together for the nucleus, then arrange the electrons as described in orbits around the nucleus.
Rutherford pictured the atom as a miniature solar system, with a dense positively charged nucleus at the center and electrons orbiting around it in fixed paths. This model is known as the Rutherford model of the atom.
Rutherford's model of the atom was incomplete. He proposed a model in which electrons orbit the positively charged nucleus like planets around the sun. However, this model failed to explain the stability of the atom and the energy levels of electrons. It was later improved upon by Niels Bohr's model, which incorporated quantum mechanics concepts to explain these phenomena.
De Broglie proposed that electrons in Bohr's model of the atom have wave-like properties, which helps explain the fixed energy levels.
Erwin Schrodinger proposed the modern atomic model, known as the "wave-mechanical" model. Essentially, he said that atoms behave like both waves and particles, and purported the concept of electron shells, subshells, and orbitals. Electrons are found on "shells" of charge outside the atom. These shells divide into subshells, which divide into orbitals.

The Bohr-Rutherford model is an old model of atomic structure that represents an atom as a nucleus surrounded by electrons in specific energy levels or shells. Iron, with atomic number 26, would have 26 electrons orbiting the nucleus in shells or energy levels. This model helped explain the stability and spectral lines of elements like iron.
You need naked iron, in an environment containing oxygen (like most outside air, or water). Steel is carbon saturated steel. Oxygen can't easily bind with the iron elements in steel, as carbon has a stronger bond, and even if an oxygen atom would pull out another atom out of the steel it would be a carbon atom, not an iron one.
Niels Bohr suggested a planetary model for the atom.

No.
To explain atomic emission spectra. Using the Bohr Model of a hydrogen atom, deriving the frequency of these emission lines is almost trivial. Without the Bohr Model, deriving them is impossible. Also, the "classical" model of electrons in an atom, acting like planets around a nucleus, would result in complete collapse of such an atom in a small fraction of a second.

J.J. Thompson's model of the atom, often refered to as the "plum pudding model" due to it's random distribution of electrons throughout the atom, suggested that negatively charged electrons were scattered about a positively charged jelly-like substance, with the charge from the positive material canceling out the negative charge from the electrons.
The Billiard Ball Model is John Dalton's idea of what an atom looks like.
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
It is true. A compound contains two or more different type of atoms.
