  • Acid Base Neutralization Lab Report

    1001 Words  | 5 Pages

    Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter. Its pH is

    Plutonium 1. Identifies a radioisotope that could be used as a fuel to produce electricity in Australia Plutonium 239 is a radioactive isotope that is a possible fuel source that could be used to produced electricity in Australia. 2. Describes how the isotope is produced (from raw materials) This element can be found naturally occurring in the earth's crust. Due to its relatively short half-life, it decays before it can be mined, extracted and used. It can also be found in trace amounts within

  • The Mpemba Effect: Hot Water Freezes Faster Than Cold Water

    1149 Words  | 5 Pages

    The Mpemba effect is that, under certain circumstances and experimental parameters, it is observed that hot water freezes faster than cold water which sounds implausible since hot water, with a higher temperature than cold water, has a higher amount of internal energy which has to be lost before it starts to change its state and turn into ice. The effect got its name from Erasto Mpemba who discovered the effect that hot water freezes faster than cold water after he discovered that hot ice-cream freezes

  • Advantages And Disadvantages Of Radiopharmaceuticals

    784 Words  | 4 Pages

    Isotopes are atoms that contain the same number of protons but have different numbers of neutrons (What is Isotope). These isotopes contain similar chemical properties but have different physical properties due to their atomic mass. Or in other words, isotopes have the same atomic number but differ in mass (What is an Isotope). “There are 90 naturally occurring elements with roughly 250 stable isotopes, and over 3200 unstable or radioactive isotopes” (Why are Isotopes Important). A stable isotope

    00. These are only 3 of the many atomic masses present. We only talk of average masses here because many elements consist of mixtures of atoms that have identical chemical properties but differ in mass. We will later dwell on this topic later on "Isotopes." You can also use atomic weight (this unit does not have an abbreviated form), but it is advised to stick with atomic mass, for accuracy and

  • The Manhattan Project Einstein Analysis

    2120 Words  | 9 Pages

    These were both nuclear bombs but they were powered differently. The first one "Little Boy" was driven by the isotope uranium-235. "Little Boy" was a gun type of bomb. For it to work there must be a sub-critical projectile and a sub-critical target. When they met this would in turn create a critical mass, then the chain reaction starts and then releases high amounts

  • Molybdenum Research Paper

    536 Words  | 3 Pages

    Molybdenum was discovered by Carl Wilhelm Scheele in 1781 (“WebElements Periodic Table”). Molybdenum’s symbol, Mo, is fairly similar to its name. Boasting atomic number 42, Molybdenum sits in group 6, period 5, and is labeled as a transition metal, generally classified just as a metal (“Royal Society of Chemistry”). Though it doesn’t have any special roles in history, it is a very important element in today’s world, and has been since the manufacturing of steel became a big business. Its current

  • Compare And Contrast Fission And Nuclear Fusion

    792 Words  | 4 Pages

    In this day and age where energy is one of the greatest factors in world events, it is unsurprising to see nuclear energy, the bridge between fossil fuels and renewable resources, argued for and against so fiercely. Yet under this umbrella term of “nuclear energy” that people enjoy throwing around, there are two wildly different forms of energy. Things that perhaps shouldn’t be lumped together so haphazardly. Those are Nuclear Fission and Nuclear Fusion. In contrast to their similar names, fission

  • Plutonium Dangerous Element

    produced by G.T. Seaborg, J.W. Kennedy, E.M. McMillan, and A.C. Wohl in 1940 (Helmenstine). It was occasionally difficult to create another element. However, these four scientists managed to create the element plutonium. They did this by shelling an isotope of uranium (U-238) with deuterons that had been quickened in a device called the cyclotron ("It 's Elemental".). Thanks to this result, Neptunium-238 was created along with two other neutrons. However, even though plutonium was originally created

  • Pros And Cons Of The Dinosaurs

    1177 Words  | 5 Pages

    Ever since the knowledge about the existence of the gigantic living forms has been perceived by human kind, our ever-curious mind has arisen several baffling questions about them – THE DINOSAURS. One of the most debated issues about the dinosaurs is their thermoregulatory system. As much as it has aroused our tickling mind, it has also given way to different hues of thoughts leading to a bedlam of discussions. In the following discussion, I have tried to brush against some of them through counter-

  • Famous Influences In Ernest Rutherford's Experiments

    He also foresaw that economies based on non-renewable fuels were self-destructive. Soddy was and still is a successful scientist of the atomic model and theory thanks to his findings of isotopes. The same elements exist in different forms, with nuclei having the same number of protons but different numbers of neutrons. This changed the theory of the atomic model. Soddy used the rather basic tools and used the ones available to him.

    Isotopes of the same element have the same amount of protons, but different amounts of neutrons. Different isotopes of the same element differ in atomic mass because of the change in number of neutrons, but still hold the same chemical properties. An ion is where an atom is missing or has extra electrons, which

  • Pros And Cons Of Sulphur

    1234 Words  | 5 Pages

    Sulphur is a yellowish, non-metallic chemical element in the periodic table. It is found in group 6 and period 3. Sulphur is identified by the letter S. Since Sulphur is the 16th Element of the periodic table therefore atomic number is always similar as the proton number which is located in the nucleus and converts the nucleus in to a positive charge as neutron is a neutral charge (+-) so positive (+) plus neutral (+-) equals a positive charge. The atomic mass for sulphur is 32 amu or (Atomic Mass

  • Essay On Radioactive Dating

    1791 Words  | 8 Pages

    (2005) states that ‘Not only is the carbon atom the building block of life (…) it also provides us with a means of dating life’. Radioactive dating is based on the disappearance or development of an isotope because of radioactive decay (for example, artificially produced isotopes 137Cs/134Cs). Isotopes are atoms of elements with different numbers of neutrons. An atom is the smallest unit that defines the chemical elements and their atoms. The nucleus is situated at the centre of an atom and contains

    , p. 2). Gamow’s research then ventured to the “Exploration and Discovery” part of the flow chart, by asking questions about the abundance of heavier elements, and by making observations on his problems. For example, he explained that “no stable isotopes exist at the masses of five and eight” (Williams et al., n.d, p. 2). Gamow then returned to asking more questions and making more observations on Quantum
