Discovery of Proton and Neutron

Science > Physics > Nuclear Physics > Discovery of Proton and Neutron Before the discovery of the atomic nucleus, there were ideas that all atoms are composed of hydrogen atoms (called by William Prout “protyles”). This hypothesis is known as Prout’s hypothesis. According to this hypothesis, the hydrogen atom was the only truly fundamental particles, […]

Nuclear Structure

Science > Physics > Nuclear Physics > Nuclear Structure In this article, we shall discuss the composition of nucleus and concept of nuclear radius, nuclear vlume, and nuclear density. Geiger Marsden Experiment: A narrow beam of alpha particles from the radioactive source was incident on a thin gold foil. The scattering of alpha particles takes […]

Concept of Radioactive Decay

Science > Physics > Nuclear Physics > Concept of Radioactive Decay Transformation of radioactive element into another element (radioactive or non-radioactive) is known as radioactive decay or disintegration. In radioactive decay, the nucleus of a radioactive element called parent undergoes a spontaneous change accompanied by the emission of radiation and the formation of the nucleus […]

Natural Radioactivity

Science > Physics > Nuclear Physics > Natural Radioactivity Radioactivity was discovered by French physicist Antoine Becquerel in 1896. He found that certain compounds of uranium emitted invisible radiations which affected photographic plates. It is also found that Thorium and its compounds also show these properties. Madame Curie and Piere Curie discovered two elements namely […]
