  • Properties Of The Elements
    679 words
    Dimitri Mendeleev & The Periodic Table Derived by Dimitri Mendeleev, the periodic table may be one of the most informational tables contained in chemistry. By leaving gaps in the columns and rows, Mendeleev was allowing for the discovery of undiscovered elements of that time. From the properties of the elements surrounding these gaps, Mendeleev was able to predict the properties of these undiscovered elements. Finally, when other scientists discovered the tools of the periodic table, Mendeleev's...
  • Length At 0 1 M The Period

    An investigation on the factors affecting the period of one complete oscillation of a simple pendulum In this investigation I aim to discover and investigate the factors which affect the time for one complete oscillation of a simple pendulum. It is important to understand what a pendulum is. A simple pendulum is a weight or mass suspended from a fixed point and allowed to swing freely. An oscillation is one cycle of the pendulums motion e.g. From position a to b and back to a. The period of osci...

  • History Of The Periodic Table Of Elements
    695 words
    Things are very different from each other, and can be broken down into small groups inside itself, which was then noticed early by people, and Greek thinkers, about 400 BC. Which just happened to use words like 'element', and 'atom' to describe the many different parts and even the smallest parts of matter. These ideas were around for over 2000 years while ideas such as 'Elements' of Earth, Fire, Air, and Water to explain 'world stuff' came and went. Much later, Boyle, an experimenter like Galil...
  • Of The Popular Styles
    469 words
    The Federal Period The time after the Revolutionary War when America was beginning a new consciousness, marked by its recently acquired independence, was called the Federal Period. American furniture makers still modeled designs from England but soon created styles with balanced proportions and symmetrical lines associated with classical design. Styles were generally named for the monarchs who reigned or for the design influences that prevailed at the time the style was introduced. There was usu...
  • Periodic Table Of The Elements
    867 words
    Chemistry November 18, 2002 The Periodic Table of Elements In September 1860 the birth of the Periodic table began. A group of the world's best chemists assembled in Germany to discuses the issues of atomic mass. At this meeting an Italian chemist, Stanislao Cannizzaro, introduced the right way to accurately measure the relative mass of an atom. After the new method was introduced chemists started to recognize similarities in the properties of various elements and placed them into families. In t...
  • Periodic Arrangement Of The Elements
    373 words
    In the early 1800's, many attempts were made to organize the arrangement of the elements. By 1869 a Russian by the name of Dmitri Mendeleev published a periodic arrangement of the elements based in increasing atomic mass and in 1871 Mendeleev published a more elaborate table which was the prototype of the modern periodic table. In Mendeleev's table, he had also grouped the elements by matching similar properties. Although his table seemed to be ideal, there were many missing pieces. Mendeleev ex...
