    The radioactive source in a smoke detector is americium-241. Americium-241 is an alpha emitter. The alpha particles ionise the molecules of the air forming ions and electrons which are attracted to a pair of charged plates as shown in the picture below. When the ions and electrons hit the plates they provide a small amount of electricity (a small current). This current stays constant and is monitored by the smoke…

    118 Elements

    • 1396 Words

    How is it that 4 out of the 118 elements comprise over 96% of all living organisms? It is due to their reactive nature and ability to form bonds. One might ask why or how they are so reactive with other elements. Just as anything else in the universe seeks stability, so do atoms. Each of these 4 atoms seeks stability through their electrons. For example, hydrogen has 1 electron in its valance shell and it has the ability to fill that shell with up to 2 electrons thus it seeks another atom that also has 1 electron in its valance shell to create stability. Another prime example is carbon, which has 4 electrons in its valance shell. It then seeks an atom with 4 electrons in its valance shell to create stability. These 4 elements are the…

    Radioisotopes

    • 9133 Words
    • 37 Pages

    adioisotopes: What Are They and How Are They Made?What are isotopes?The isotopes of an element are all the atoms that have in their nucleus the number of protons (atomic number) corresponding to the chemical behavior of that element. However, the isotopes of a single element vary in the number of neutrons in their nuclei. Since they still have the same number of protons, all these isotopes of an element have identical chemical behavior. But since they have different numbers of neutrons, these isotopes of the same element may have different radioactivity. An isotope that is radioactive is called a radioisotope or radionuclide. Two examples may help clarify this.The most stable isotope of uranium, U-238, has an atomic number of 92 (protons) and an atomic weight of 238 (92 protons plus 146 neutrons). The isotope of uranium of greatest importance in atomic bombs, U-235, though, has three fewer neutrons. Thus, it also has an atomic number of 92 (since the number of protons has not changed) but an atomic weight of 235 (92 protons plus only 143 neutrons). The chemical behavior of U-235 is identical to all other forms of uranium, but its nucleus is less stable, giving it higher radioactivity and greater susceptibility to the chain reactions that power both atomic bombs and nuclear fission reactors. Another example is iodine, an element essential for health; insufficient iodine in one 's diet can lead to a goiter. Iodine also is one of the earliest elements whose radioisotopes were used in what is now called nuclear medicine. The most common, stable form of iodine has an atomic number of 53 (protons) and an atomic weight of 127 (53 protons plus 74 neutrons). Because its nucleus has the "correct" number of neutrons, it is stable and is not radioactive. A less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons). With "too many" neutrons in its…

    1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge, surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal.…
