Hantaro Nagaoka

GENERAL INFORMATION

• Hantaro was born August 15, 1865
• He died December 11, 1950 in Tokyo
• His nationality is Japanese.

CONTRUBUTIONS

• Nagaoka created the Saturnian atomic model. This model was named after planet Saturn because it acted like a mini solar system.
• This model presented the idea of a positively charged nuclear with negatively charged electrons orbiting the nucleus.
• These electrons were to be arranged at equal angular intervals in a circle. They repel off of each other with electrostatic forces.
• Nagaoka also showed that for certain circumstances the ring structure would be unstable and cause destruction.
• Atomic radiation would occur.

NAGAOKA'S CONCLUSIONS

• Nagaoka worked in the field of physics and was a professor at the Imperial University of Japan.
• Nagaoka made his conclusions with logic.
• He also used much information from his career as a physicist.
• No experiments were recorded for Nagaoka's work.
• The First International Congress of Physics in Paris got him interested.

ACCEPTED OR REJECTED?

• Nagaoka's theory was used by many scientists throughout the research of the atomic theory.
• Although, his theory is not used today.
• Such a system says that the electrons will never rest.
• Electrons will become exhausted of energy by radiation.
• Charged rings would be unstable due to repulsive disruption.

EXTRA INFORMATION

• Nagaoka abandoned his work in 1908.
