The electron configuration of platinum is: [Xe]4f145d91.
Niels Bohr suggested a planetary model for the atom.
The Bohr atomic model is similar to solar system.
Niels Bohr created this model; electrons move around the positive atomic nucleus.
The Bohr model of germanium is a simplified representation of the germanium atom proposed by Niels Bohr in 1913. It describes the electrons in germanium atoms as orbiting the nucleus in fixed circular paths, or energy levels, and helps explain the electronic structure of germanium. The model was an important step in the development of quantum mechanics.

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.

The Bohr model of the atom, which placed electrons at specific energy levels around the nucleus, is known as the planetary model of the atom. In this model, electrons orbit the nucleus in fixed paths or "shells."

Bohr's atomic model was based upon a famous experiment by Rutherford, who determined that an atom has a small, dense, positively charged nucleus surrounded by negatively charged electrons. Bohr took this information and came up with a "planetary" model where electrons orbit the nucleus in set paths, much like the planets orbit the sun. We now know this is inaccurate, but Bohr's model is still used in teaching because it's a handy way to keep track of how many electrons are in which energy level.
