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 quantum mechanical model of the atom was developed by Erwin Schrödinger in 1926. His work built upon the earlier discoveries of other scientists, such as Max Planck and Albert Einstein, in the field of quantum mechanics.
The three scientists who played a major role in developing the wave mechanical model of the atom were Erwin Schrödinger, Werner Heisenberg, and Max Born. Their work revolutionized our understanding of the behavior of electrons in atoms.
The current atomic model is called the electron cloud model because it describes electrons not as particles located at specific positions, but as existing within a cloud-like region around the nucleus, where they are most likely to be found. This model acknowledges the dual wave-particle nature of electrons and provides a more accurate representation of their behavior in an atom.

The electron cloud theory was developed in the late 1930s and early 1940s.
The Electron Cloud Model was proposed by Erwin Schrödinger in 1926 as part of the development of quantum mechanics. It describes electrons not as discrete particles with defined orbits but rather as wave functions that exist in a three-dimensional cloud surrounding the nucleus of an atom.
Erwin Schrodinger
All matter is composed of atoms. An atom consists of a nucleus (it contains the positively charged neutrons). The electrons orbit the nucleus in a ring, therefore we refer to the electrons as the electron cloud.

Erwin Schrodinger invented the model of the atom based on research done by scientists such as Niels Bohr.
It was Erwin Rudolf Josef Alexander Schrödinger who first wrote the electron wave equations that led to the Quantum Mechanical model. He formulated it in late 1925, and published was published 1926.
The quantum mechanical model, also known as the electron cloud model, replaced Bohr's model of the atom. This model represents electrons as existing in a diffused cloud of probability in specific energy levels around the nucleus rather than in fixed orbits.
