The Nagaoka model and the Thompson model are both theoretical frameworks used to describe the behavior of electrons in solid-state physics, particularly in the context of superconductivity. The Nagaoka model focuses on the effects of strong correlations in systems with a single hole in a half-filled band, emphasizing the role of magnetic interactions. In contrast, the Thompson model is often associated with the study of electron-phonon interactions and their impact on superconducting properties, particularly in layered materials. Overall, the key difference lies in their focus: Nagaoka emphasizes magnetic correlations, while Thompson addresses electron-phonon coupling.

What did Nagaoka do and in what year?
Hantaro Nagaoka was born in Nagasaki, Japan on August 15, 1865. He went to Tokyo University and got his Bachelors degree went to later colleges such as universities of Berlin, Munich, and Vienna. Then he attended the First International Congress of Physicists in Paris in 1990. After that he started getting interested in the Atomic Theory. His interest in the atom theory led to Nagaoka wanted to disprove J.J. Thompson's theory wrong. Thompson's theory stated that opposite charges are impenetrable. He proposed a different model in which a positively charged center is surrounded by multiple revolving electrons, of Saturn and its rings. Nagaoka used Saturn's rings as a metaphor for the position and movement of electrons in the atom. In this model electrons are orbiting bodies around positivly charged nucleus that is the planet. This model was proposed in 1903. He called this model the "Saturnian"model. Nagaoka later did research in spectroscopy and other fields. In 1909, he published a paper on the inductance of solenoids. In March 1924, he described studies in which he claimed to have successfully formed a milligram of gold and some platinum from mercury. Nagaoka was granted the Order of Culture by the Japanese government in 1937. He also got rewarded for his scientific work by the Nagaoka Crater, which is a crater on the moon that is named after him.
How did Nagaoka contribute to the atomic theory?
He contriubuted to modern science with his model for atomic theory which he described was similar to the rings of saturn and he descibed that in his model of atomic theory. Hantaro Nagaoka was a great man and and he contributed alot of tings to modern science i cant name them all but he contributed alot of things to modern science
What changes were made to Thomson’s “raisin bun model”?
In 1904, the Japanese physicist Hantaro Nagaoka changed Tomson's model with the following: Nagaoka atom resembled a miniature solar system whereas Tomson's was a positively charged sphere in which negatively charged electrons were embedded. Nagaoka's model had the atom in the middle, and the negatively charged electrons circling it like the planets orbit the sun, and Tomson's had the negatively charged electrons embedded into the atom.
When was electron cloud model first described?
Very probable Hantaro Nagaoka in 1904.

What is an fact about hantaro nagaoka?
Hantaro Nagaoka was a Japanese physicist known for his contributions to the field of atomic physics and his proposal of the "Nagaoka model" of the atom in 1904, which suggested that electrons orbit a central nucleus in a manner similar to planets around the sun. He was one of the early advocates for the idea of an atomic structure that included a nucleus, predating the more widely accepted Rutherford model. Nagaoka's work laid the groundwork for later developments in atomic theory and helped to shape modern understandings of atomic structure.

Well, if you live in Bluffton, SC and your teacher is Mr. Thompson, then you're out of luck, I'm doing that homework right now, can't find the answer, ;) see you in class tomorrow!
