    pressures. That is, until now. Recently this year, hydrogen was changed into a metallic substance, which could conduct electricity. An experiment conducted by William J. Nellis et al. at the Lawrence Livermore National Laboratory accomplished this feat. Hydrogen was converted from a non-metallic liquid, into a liquid metal. The likelihood that the most abundant element in the universe could be converted into metallic form at sufficient pressures was first theorized in 19351, but tangible evidence

    The Molten Core Theory The center of the Earth is composed of a solid metallic core surrounded by a molten layer of liquid metal. This paper will discuss the reasons to believe the theory that the Earth has a molten core, and the important discoveries that have led to this generally accepted theory. It is very reasonable to agree with this theory when paying credence to the logical evidence that answers questions about the Earth’s core. This evidence includes information about the elemental

    are: Ore, Limestone and Coke. A burst of hot, oxygen enriched air is blown into the air-blast nozzle located at the near bottom of the furnace. What follows are a number of oxidation and reduction type reactions which ultimately produce the metallic iron. [IMAGE] One of these reactions is the coke being burnt. The heat generated by this reaction increases the bottom of the furnace to a temperature near 19000° C. This reaction is represented in a chemical equation: C(s) + O2(g) ® CO2(g)

    negatively charged electrons Metallic Bonding - They conduct electricity due to a sea of delocalised electrons - They have a lattice of positive atoms. - Transition metals contribute both S and D electrons in the sea of electrons - The attraction is between the ions and mobile valence electrons and not between the layers, this means they can bend over each other - The large the number of valence electrons and the smaller the atoms and the stronger the metallic bonding Covalent bonding - Between

    • 2 Pages

    Plutonium Plutonium is a radioactive metallic element. Although it is occasionally found in nature, mostly all of our plutonium is produced artificially in a lab. The official chemical symbol for plutonium is Pu, coming from its first and third letters. Its atomic number is ninety-four. Plutonium is able to maintain its solid state until very high temperatures, melting at six hundred and forty degrees Celsius, and boiling at three thousand four hundred and sixty degrees. The density of Plutonium

In one hand I have my books that I 'attempted' to read for homework the previous night and my other hand is holding on to my Sony metallic cd player for my bus ride to school. My peers and acquaintances wait for my arrival on the yellow school bus expecting me to begin their day off by cracking few jokes and sharing stories of my wild weekends. Only I wish they would know that not all

    Metallic glass Metallic glass or amorphous metal is a metal that when melted will be cooled rapidly to disorganize the particles in an atomic scale. Due to the particles being stable yet unorganized, the metal or alloy this metal or alloy will send kinetic energy back to anything it hits making it bounce or proceed further and longer. Originally used for missiles and space discoveries, this metal is very flexible and is good for low temperature environments because of the disorganizations of particles
