Hace 2 días · CONCLUSIÓN. El modelo atómico de la mecánica cuántica representa un avance monumental en nuestra comprensión de la materia a nivel subatómico. Partiendo de los primeros modelos atómicos de Dalton, Thomson y Rutherford, cada uno contribuyó con ideas fundamentales, pero también presentaron limitaciones que no podían explicar completamente las observaciones experimentales.
Hace 2 días · In 1897, J. J. Thomson discovered that cathode rays are not a form of light but made of negatively-charged particles because they can be deflected by electric and magnetic fields. He measured these particles to be at least a thousand times lighter than hydrogen (the lightest atom).
Hace 3 días · The charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons.
Hace 6 días · William Thomson, 1st Baron Kelvin, OM, GCVO, PC, FRS, FRSE (26 June 1824 – 17 December 1907) was a British mathematician, mathematical physicist and engineer born in Belfast.
Hace 3 días · Evolução dos modelos atômicos – J. J. Thomson Portanto, o modelo atômico de Dalton precisaria ser substituído por um novo modelo, que ficou conhecido como pudim de passas (mais próximo, talvez, de um panetone!). Nesse modelo, o átomo é uma esfera de carga positiva com partículas de carga negativa incrustadas (passas ou frutas!).
Hace 5 días · Freeman John Dyson FRS (15 December 1923 – 28 February 2020) [1] was a British-American theoretical physicist and mathematician known for his works in quantum field theory, astrophysics, random matrices, mathematical formulation of quantum mechanics, condensed matter physics, nuclear physics, and engineering.
