Introduction In “The Radioactive Boy Scout”‚ by Ken Silverstein‚ a small town boy-named David Hahn-dives into the experimental world of not only chemistry but nuclear engineering. In this atomic novel the reader delves deep into the world of a child prodigy and the tale of nuclear romance. This radioactive account of a boy’s journey from small town chemist to a star-crossed engineer is nothing short of explosive. Key Idea 1 In the early chapters of the book David Hahn was found mixing various chemicals

The Half-Life of a Radioisotope CHM 152 Abstract: The half-life of an unknown radioactive isotope was investigated. The activity of the samples through use of a Geiger-Muller counter. The activity was measured for approximately five minutes per sample‚ and a half-life was calculated by the unknown. The results were calculated to indicate a half-life of 6.65 days of the unknown radioisotope. Introduction: The half-life of a radioisotope is defined as the amount of time necessary for one-half

Katie Jones Mr. Sanders Chemistry 8 November‚ 2015 “The Radioactive Boy Scout” Introduction “The Radioactive Boy Scout” by Ken Silverstein is a true story about a man named David Hahn. The story starts out in Michigan when David still attended high school. His goal was to create a “fast breeder reactor” in the shed out behind his house. David’s whole reason for his backyard experiment was to earn a badge for his boy scout organization. However‚ later in his life‚ he became very intrigued

Isotopes are different forms of a Single element. Elements and their uses to our human body Oxygen is the third most abundant element found in the sun‚ and it plays a part in the carbon-nitrogen cycle

Chemistry Changes Everything: ¹ᶟ¹I - Iodine¹ᶟ¹ An isotope is two or more forms of an element where the nuclei of the element has more neutrons than protons and normally each element only has one stable isotope of the element. Changing the neutrons in the atom also changes the atomic mass but not chemical properties. Radioisotopes are radioactive versions of an isotope where the atom or element has an unstable nuclei therefore emitting radiation. An unstable nuclei is created when there is either

There are many types of radiation and radioactive emissions in the world wide that can be used in medicine. Iodine-131 has a big effect and usage for medicine where it has 53 protons‚ 53 electrons and 78 neutrons. Iodine-131 has varied uses in medicine where it is utilized as a part of atomic pharmaceutical restoratively and can likewise be seen with symptomatic scanners in the event that it has been utilized remedially. Iodine-131 they can be promptly followed even in moment amounts with such discovery

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
