Who made the statement that the distance of an electron from the nucleus dpends on the energy of the electron?

The statement that the distance of an electron from the nucleus depends on the energy of the electron is rooted in quantum mechanics and is often attributed to the principles outlined by physicists such as Niels Bohr and later developments in quantum theory. In Bohr's model of the atom, electrons occupy specific energy levels or orbits, with the distance from the nucleus correlating to these energy states. Higher energy levels correspond to greater distances from the nucleus.
