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.
