What did Hantaro Nagaoka discover about the atom?
Japanese physicist Nagaoka Hantaro in particular developed the “Saturnian” system in 1904. The atom, as postulated in this model, was inherently unstable because, by radiating continuously, the electron would gradually lose energy and spiral into the nucleus.
What is the Saturnian model?
His model was known as the Saturnian model of the atom and according to this model the atom consists of a massive positive centre surrounded by a number of orbiting electrons, in the manner of Saturn and its rings. …

When did Hantaro Nagaoka postulate a Saturn like atom?
A competing model had been proposed in 1903 by Hantaro Nagaoka, who postulated a Saturn-like atom, consisting of a positively charged sphere surrounded by a halo of electrons. Figure 1.7. 1: Thomson’s Plum Pudding or Chocolate Chip Cookie Model of the Atom. In this model, the electrons are embedded in a uniform sphere of positive charge.
What kind of atomic model is Nagaoka’s?
Thus, Nagaoka’s mode l is also called Saturnian model. Nicholson’s and Niels Bohr’s, it differed from →Bohr’s atomic model in crucial points. Unlike correlated with the electron’s orbit frequency.
Why did Hantaro Nagaoka reject the plum pudding model?
In 1903, Thomson had suggested that the atom was a sphere of uniform positive electrification, with electrons scattered through it like plums in a pudding, giving rise to the term plum pudding model . Nagaoka rejected Thomson’s model on the grounds that opposite charges are impenetrable.
Who was Hantaro Nagaoka and what did he do?
Hantaro Nagaoka (長岡 半太郎, Nagaoka Hantarō, August 19, 1865 – December 11, 1950) was a Japanese physicist and a pioneer of Japanese physics during the Meiji period . Nagaoka was born in Nagasaki, Japan on August 19, 1865 and educated at the University of Tokyo.
