    Yafaa Chaudhary PHYSICS 5 NOTES Physics 5 3.5.1 Radioactivity Evidence for the nucleus Qualitative study for the Rutherford scattering. Rutherford directed a narrow beam of α-particles‚ all of the same kinetic energy‚ in an evacuated container at a thin gold film‚ in order to identify the structure of an atom:  The α-particles need to be of the same kinetic energy otherwise slow α-particles would be deflected more than faster α-particles on the same initial path.  The container needs to be evacuated

    NUCLEUS The positively charged dense central part of an atom. In Biology the term first introduced by Miescher‚ employed to describe a structure round in the cells of with the tissues of animals and plants are composed. In general it is a viscous spherical body containing a structure known as the plasmosome or nucleolus and a tangle of material chromatin characterized by a special affinity for basic dyes‚ usually spherical mass of protoplasm found in the most living cells that directs the activities

    protons. Located in the atom’s nucleus‚ protons and neutrons are referred to as nucleons. The electrons rest outside of the nucleus at various energy levels (orbitals). Most of an atom’s mass comes from its very small nucleus‚ whose protons and neutrons each have a mass of approximately 1 u (atomic mass units). Electrons‚ on the other hand‚ have a mass of around 0.0005 u – almost negligible compared to the masses of a nucleon. Each subatomic particle carries a specific charge. Electrons are considered

    protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon is a particle found in the nucleus i.e. a proton or a neutron. In general‚ if N is the neutron number of an element‚ then A=Z+N In an atom the number of protons is equal to the number of electrons. Nuclide notation A nuclide is a form of an element. If X is a given nuclide with proton number Z and nucleon number A‚ then its nuclide notation

    Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the
