Ernest Rutherford developed the first nucleus and electron model of the atom. It was based on experiments conducted by Geiger and Marsden.
Heisenberg and Schrodinger developed the electron cloud model using quantum mechanical probability functions to determine the the regions, or clouds, in which electrons would most likely be found outside of the nucleus.
The first atomic model based on experimentation was developed by J.J. Thomson in 1897. Thomson's model, known as the "plum pudding model," proposed that atoms were made up of a positively charged material with negatively charged electrons scattered throughout, similar to the seeds in a watermelon.
Protons and Neutrons and on the outside they are Electrons.
The first model of the atom that illustrated its internal structure was developed by Ernest Rutherford in 1911. Through his gold foil experiment, Rutherford proposed that atoms consist of a dense nucleus containing protons, surrounded by a cloud of electrons. This model replaced the earlier plum pudding model by J.J. Thomson, significantly advancing the understanding of atomic structure.

The first model of the atom was developed through the discovery of subatomic particles such as electrons, protons, and neutrons. This led to the development of the planetary model of the atom proposed by Niels Bohr in 1913.

Niels Bohr developed the model of the atom shown in the image. He proposed the planetary model of the atom, where electrons orbit the nucleus in fixed energy levels.
The scientist that developed the iconic atom model that depicts a nucleus surrounded by electrons was Ernest Rutherford. Rutherford developed the model in 1911 after displaying some experiments that showed that the J.J.Thomson model was incorrect. Rutherford's experiment showed that an atom is a small but heavy central particle and is surrounded by a cloud of electrons. This was the opposite of what Thomson's model proposed.
The first shell in a Bohr model can hold a maximum of 2 electrons.
The scientist that developed the orbital model is Niels Bohr
