Recent questions

• What is the Thomson model?

  The Thomson model, proposed by J.J. Thomson, describes an atom as a positively charged sphere with electrons scattered throughout, similar to raisins in a pudding. This model was later replaced by the Rutherford model.

• What is a neutron?

  A neutron is a subatomic particle found in the nucleus of an atom. Neutrons have no electric charge and are crucial for stabilizing the nucleus along with protons.

• Who proposed the Thomson model?

  The Thomson model was proposed by J.J. Thomson, a British physicist, in the early 20th century. He suggested that atoms were composed of a positively charged sphere with electrons embedded in it.

• What is the significance of the neutron in an atom?

  Neutrons play a vital role in stabilizing the nucleus of an atom. Along with protons, neutrons help maintain the structure of the nucleus and contribute to the overall mass of the atom.

• How did J.J. Thomson describe the atom in his model?

  J.J. Thomson's model of the atom likened it to a positively charged sphere with electrons dispersed throughout, similar to the distribution of raisins in a pudding. This model was a precursor to the more detailed atomic models that followed.
