    Atoms Atom is the fundamental building block of all stuff‚ or what scientists like to call "matter". An individual atom is very small. In fact‚ the smallest type of atom‚ hydrogen‚ has a diameter of 10-8 cm. Every single object is composed of atoms. Our body is made up of many‚ many individual atoms. There are also many different types of atom. These different types are called elements. Examples of some elements are hydrogen‚ oxygen‚ and helium. Under normal conditions many atoms can stick together

    The PET scan‚ or Positron Emission Tomography‚ was born in 1973 at Washington University. It was created by Edward Hoffman‚ Michael M. Ter-Pogossian‚ and Michael E. Phelps; Phelps is most often credited with the invention (History of PET and MRI‚ 2009). In preparation for a PET scan‚ radioactive tracers are injected into the body‚ inhaled‚ or ingested by the patient through a solution that they drink. Then the scan will actually begin‚ as the patient lies on a table‚ which glides into the machine

    cannot break it any further? Democritus thought is eventually had to be unbreakable. He finally concluded that at some point there is the smallest bit of matter and he called these basic particles atoms. Today we know that Atoms contain protons‚ neutrons‚ electrons‚ and a nucleus. The nucleus is in the center of the atom. It is so small that its diameter is 100‚000 times smaller than its atom. Electrons float around the nucleus and determine the chemistry of an atom. Here’s a fun fact for you. Did

    Isotopes in Agriculture An isotope is a two or more atom that has different mass number but the same atomic number. An isotope is a variation of an element with a difference in the normal number of neutrons. The increased mass of an isotope can cause the chemical reactions they are used in to progress more slowly than a reaction that does not use isotopes. Not all isotopes are radioactive and there are many uses for them. They can be used in medicine‚ diagnose‚ nutrition‚ agriculture‚ research

    Today‚ many countries are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs

    Isotopes of Paperclipium Purpose: To determine the isotopic composition of the element‚ paperclipium. Background Information: Isotopes are atoms of the same element with the same proton number but different mass number; that is‚ the number of neutrons differ. Isotopes of the same element have the same electronic configuration as they have the same number of electrons. This accounts for the fact that their chemical properties are the same‚ as the react similarly. However‚ their physical properties
