Who discovered plum pudding model?
J.J. Thomson’s
Summary. J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.”
How was the Bohr model discovered?
It was while Bohr was working in England in 1913 that he developed this atomic model. He developed the model after studying the way glowing, hot hydrogen gives off light. When an incandescent light bulb is lit, it gives off all the different wavelengths of light.
When was the Bohr model created?
1913
In July of 1913, Danish physicist Niels Bohr published the first of a series of three papers introducing this model of the atom, which became known simply as the Bohr atom.
Why was the plum pudding model given that name?
The plum pudding model (also known as Thomson’s plum pudding model) is a historical scientific models of the atom. The plum pudding model is defined by electrons surrounded by a volume of positive charge, like negatively-charged “plums” embedded in a positively-charged “pudding” (hence the name).

¿Qué es el modelo de Bohr?
Además, el modelo de Bohr incorporaba ideas tomadas del efecto fotoeléctrico, explicado por Albert Einstein . Bohr intentaba hacer un modelo atómico capaz de explicar la estabilidad de la materia y los espectros de emisión y absorción discretos que se observan en los gases.
¿Qué pasó con Robert Bohr en la Segunda Guerra Mundial?
En 1943, con la Segunda Guerra Mundial en pleno apogeo, Bohr escapó a Suecia para evitar su arresto por parte de la policía alemana, viajando posteriormente a Londres.
