    it from a certain distance. Saturn rotates quickly‚ contributing to its high wind speeds. In addition to this‚ the heat from the planet’s interior makes its rings visible. Saturn’s atmosphere is similar to the sun’s‚ mostly containing hydrogen and helium. One of the planet’s most notable features is its rings. They can be seen from a very far distance‚ with the use of a telescope. The rings are mostly composed of particles of ice and rock. These particles are kept in the rings by Saturn’s smaller

    Through his famous 1911 gold-foil experiment‚ Earnest Rutherford‚ a former student of Thomson‚ evolved the atomic model once again. Rutherford and his colleagues fired alpha particles‚ helium atoms that had lost their two electrons‚ at a thin piece of gold foil (only 0.00004 cm in width). They used a screen coated in zinc sulfide to "catch" the alpha particles after they had penetrated the gold foil. The screen would also emit a flash of light where it was hit by an alpha particle‚ which enabled

    Fusion Nuclear Fusion Source: Atomicarchive.com at: http://www.atomicarchive.com/Fusion/Fusion1.shtml Nuclear fusion is another method to produce nuclear energy. Two light elements‚ like tritium and deuterium‚ are forced to fuse and form helium and a neutron. This is the same reaction that fuels the sun and produces the light and heat. Unlike fission‚ fusion produces less energy (~18 MeV)‚ but the components are more abundant and cheaper than uranium.

    Morris Travers in the year eighteen ninety eight. It was found in London when Sir William Ramsay made a statement that there had to be more elements because there was a gap in the Periodic Table of Elements that are like Krypton in being noble gasses helium and argon. Knowing this he was determined to find the elements that where needed to fill the gap so he did a little research. He collected information about how one element could possibly hide another element. So he thought maybe there is a new element

There were three tubes presented which contain the vapor of Hydrogen‚ Helium and Mercury. These elements can glow when connected to a voltage. Using a spectroscope‚ we will determine the types of colors and the wavelengths of the individual lines‚ which are emitted by the respective atoms. We will also examine the atomic
