    Discovery Oxygen was first discovered by two scientists. One was a British Chemist Joseph Priestly who was given credit for the discovery in 1774. The other was a Swedish Chemist Carl Wilhelm Schiele who had also discovered it around the same time as Priestly. Yet Priestly was given credit because his work, and results were published. Priestly had first found this new element when he observed that mercuric oxide, on heating. Yielded a gas that caused a flame to burn faster. He later found that ...

    Mercury Mercury is a metallic element that is a liquid at room temperature, its one of the transition elements. Mercury's atomic number is 80. It is superconductive when cooled to within a few degrees of absolute zero. Mercury was once known as liquid silver or quicksilver which was studied by the alchemists. Mercury was first distinguished as an element by the French chemist Antoine Laurent Lavoisier in his experiment on the composition of air. At room temperature mercury is a shining, moving l...

    Lawrencium There are 109 known elements, and of those, 19 of them are artificially produced or synthetic. A synthetic element is made by bombarding atomic nuclei with neutrons or other particles. The element Lawrencium has been made in this manner. While scientists continue to work to create more elements, it should be noted that most synthetic elements are so unstable, that they are of theoretical value only, and have no known practical uses. This element was discovered at the Lawrence Radiatio...

    Chapter Three Summary: Atoms and atom's structure Ancient Greek Philosophers suggested that matter was composed of individual particles, which was proved by the theory of John Dalton. The main provisions of his theory are: 1. All matter is composed of tiny, indivisible particles called atoms. 2. All atoms of a particular element are identical but the atoms of one element differ from the atoms of other element. 3. Atoms of different elements combine with each other in certain whole number propor...
  • Electrons Protons Neutrons Number

    33. Elements differ according to the number of protons their atoms contain, a value called the element's atomic number. All atoms of a given element have the same number of protons and an equal number of electrons. The number of neutrons in an atom is not predictable but is generally as great or greater than the number of protons. The total number of protons plus neutrons in an atom is called the atom's mass number. 40. Protons, electrons, and neutrons. Protons, neutrons (1 amu) and electro...
