Hace 18 horas · In 1911 Ernest Rutherford did a famous experiment using fast-moving alpha particles as bullets and very thin gold foil as a target. The results of this experiment showed that: (a) the negative and positive charges were all spread out throughout the volume of each atom (b) it was far better to use cheaper materials than gold for physics experiments

26 de jun. de 2024 · The most interesting observation was that one in 20,000 alpha particles bounced back at angles greater than 45 degrees. Some of them almost bounced back to the radiation source. Rutherford suggested that this was possible when their path is blocked by a dense and heavy particle, This led to discovery of the nucleus.
1 de jul. de 2024 · The Science and Technology Facilities Council (STFC) offer fellowships each year to early-career researchers in astronomy, solar and planetary science, particle physics, particle astrophysics, cosmology and nuclear physics. A quota system applies for each university and so the department runs an annual internal selection process for this scheme.

The primary difference between the Thomson and Rutherford atom models is that the Thomson model does not explain the atomic nucleus, but the Rutherford model does.
28 de jun. de 2024 · Ernest Rutherford discovered that hydrogen nuclei can be extracted from the nuclei of nitrogen through atomic collision and thus protons were considered as a fundamental particle or the building block of all atomic nuclei. The name proton was first given to the nucleus of hydrogen by Ernest Rutherford in 1920.
