Hace 4 días · J. J. Thomson is the Nobel Prize-winning physicist who first proved the existence of electrons and famously publicized the idea of the plum pudding model for atoms. J. J. Thomson described atoms as being positively charged spheres that contain lots of negatively charged electrons.
Hace 3 días · Most of the atom is empty space. The rest consists of three basic types of subatomic particles: protons, neutrons, and electrons.The protons and neutrons form the atom’s central nucleus. (The ordinary hydrogen atom is an exception; it contains one proton but no neutrons.) As their names suggest, protons have a positive electrical charge, while neutrons are electrically neutral—they carry ...
Hace 2 días · In 1897, J. J. Thomson discovered that cathode rays are not electromagnetic waves but made of negatively-charged particles because they can be deflected by electric and magnetic fields. He measured these particles to be several orders of magnitude lighter than hydrogen (the lightest atom). [11]
Hace 3 días · En la historia de la ciencia, se han propuesto diferentes modelos para describir la estructura del átomo, como el modelo atómico de Dalton, el modelo de Thomson, el modelo de Rutherford, el modelo de Bohr y el modelo mecánico cuántico. Cada uno de estos modelos ha aportado avances importantes en nuestra comprensión de los átomos y sus partículas.
Hace 2 días · With J. J. Thomson's discovery of the electron in 1897, it became clear that atoms were not the smallest building blocks of nature, but were rather composite particles. The newly discovered structure within atoms tempted many to imagine how the atom's constituent parts might interact with each other.
Hace 2 días · Lord Kelvin. It is believed the "PNP" in his signature stands for "Professor of Natural Philosophy". Kelvin also wrote under the pseudonym "P. Q. R." William Thomson, 1st Baron Kelvin, OM, GCVO, PC, FRS, FRSE (26 June 1824 – 17 December 1907) [7] was a British mathematician, mathematical physicist and engineer born in Belfast. [8]
