Hace 5 días · J.J. Thomson. Modelo de budín de pasas: Thomson trabajó con un tubo y rayos catódicos, que eran un haz de electrones, por lo que se le atribuye a Thomson el descubrimiento de los electrones. E. Goldstein. Descubrió los protones. Trabajó con rayos anódicos que tenían carga positiva. E. Rutherford
22 de may. de 2024 · El descubrimiento de los electrones se atribuye al científico inglés Joseph John Thomson en 1897. Thomson experimentaba con la conducción de la electricidad a través de los gases y descubrió que los rayos emitidos por un cátodo estaban compuestos por partículas de carga negativa a las que denominó “corpúsculos” .
23 de may. de 2024 · J.J. Thomson, born Joseph John Thomson, was a prominent physicist who made significant contributions to our understanding of the atomic structure and the nature of electrons. His groundbreaking experiments and discoveries paved the way for modern physics and earned him the prestigious Nobel Prize in Physics in 1906.
7 de may. de 2024 · J.J. Thomson discovered the electron, which led to the realization that atoms are divisible and contain smaller, negatively charged components. Ernest Rutherford established the nuclear model of the atom by demonstrating that atoms have a dense nucleus that contains most of their mass.
23 de may. de 2024 · In more refined experiments carried out between 1907 and 1913, the British physicist J.J. Thomson, who had already discovered the electron and observed its deflection by an electric field, passed a beam of positively charged ions through a combined electrostatic and magnetic field.
Hace 3 días · This material might all too easily be read as a conventional account centred upon some familiar ‘discovery’ pairings intruding from the 19th century: J. J. Thomson and the electron, Gregor Mendel and the gene (although Agar does not emphasize that the attribution of the electron's discovery to Thomson was as retrospectively ...
