Hace 5 días · La carga negativa de los electrones contrarresta la carga positiva de los protones, manteniendo el átomo en equilibrio.El descubrimiento de la carga y la masa del electrón fue posible gracias a experimentos realizados por científicos como Joseph John Thomson y Robert Millikan.
Hace 5 días · J.J. Thomson discovered the electron in 1897, revealing that atoms were divisible and contained smaller particles. Ernest Rutherford’s gold foil experiment in 1911 uncovered the nucleus, a dense central core within the atom.
Hace 5 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 contrived as the attribution of the discover of the gene to Mendel).
Hace 2 días · 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] He was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research and mathematical analysis of ...
Hace 12 horas · 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 4 días · To explain the distribution of electrons within an atom, J.J. Thomson proposed the Plum Pudding Model. According to this model, the atom is composed of a positively charged sphere with negatively charged electrons embedded within it, resembling plums in a pudding.
Hace 2 días · Hint: Dalton’s atomic theory proposed that all matter is composed of atoms which are indivisible and indestructible.Thomson’s model of an atom states that an atom comprises electrons distributed between a sea of protons in the same fashion as seeds in a watermelon/plum.
