Neils Bohr made the ASSUMPTION that electrons could only exist in discrete energy levels when the electrostatic field of a nucleus -- he made no attempt to show WHY this was so.
Louis de Broglie postulated that electron movement could be described as a wave, with the wavelength being equal to Planck's Constant divided by the electron's momentum. Starting with this postulate, one can derive that the only permitted radial orbits of an electron are those with a circumference equal to a multiple of these wavelengths.
Erwin Schrodinger devised a mathematical formula for which one could derive these energy levels -- and a lot more. As such, Schrodinger's Equation was more fundamental to our understanding of sub-atomic reality. Schrondinger viewed his wave function (more precisely, the product of the wave function) as the charge density of a smeared-out electron.
Although you didn't ask, it was Max Born who showed that the wave-function product was, instead, the probability of finding a point-like electron at a specific place and time.
Schrodinger and De Broglie introduced the concept of wave-particle duality and developed mathematical equations (such as the Schrodinger equation) to describe the behavior of electrons in an atom. This led to the development of quantum mechanics, which allowed for a more accurate description of electron behavior compared to Bohr's model. These contributions helped explain phenomena that the Bohr model could not, such as electron tunneling and the probabilistic nature of electron behavior.

The Schrodinger equation is from January 1926.
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.
Schrodinger's atomic model, also known as the quantum mechanical model, was better than Niels Bohr's model because it was more accurate in describing the behavior of electrons in atoms. Schrodinger's model treated electrons as waves rather than particles, allowing for a more comprehensive understanding of their behavior in complex systems. Additionally, Schrodinger's model was able to describe the probability distribution of finding an electron in a particular region around the nucleus, providing a more detailed picture of atomic structure.
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
