Oxygen was discovered by Joseph Priestly in 1774. The atomic number: 8, the atomic mass: 15.9994 AMU. The melting point is: -218.4˚C (54.750008 k, -361. 12 ˚F) The Boiling point is: -183.0 ˚C (90.15 k,-297.4˚F) Oxygen does not have a Freezing point. Joseph Priestly was born: March 13, 1733 in a country near England. He died February 6, 1804. Joseph was in the fields of science. HELIUM I chose helium because its one of the dangerous elements. Helium was discovered by Sir William Ramsay in 1895. The atomic number is 2, the atomic mass: 4.002602 AMU. The melting point is: - 272.0 ˚C (1.15 k, -457.6˚F). The Boiling point is: -268.93. Helium does not have a freezing point because it is a gas. Helium was discovered by Sir William Ramsay. Sir William Ramsay was born October 2, 1852. He died July 23, 1916. He will be remembered forever SODIUM I chose sodium because I thought it was interesting. Sir Humphrey Davey discovered sodium. The atomic number of sodium is 11. The symbol of sodium is NA.

The obtained is from liquid and air. The number of the energy level is 2. Oxygen is life!! Oxygen was found mostly everywhere in earth. Helium Helium was discovered by Sir William Ramsay in the year 1895. It’s used in balloons and deep sea diving there is way more things that use Helium. It makes your voice really squeaky some times they say that it’s bad for you! The Atomic Mass for Oxygen is 15.9994 amu. The Melting Point for oxygen is: -218.4 °C (54.750008 K, -361.12 °F). Oxygen’s Boiling Point is : -183.0 °C (90.15 K, -297.4 °F) . The oxygen’s Number of Protons/Electrons:8 and the Number of Neutrons: 8 The Classification for Oxygen is: Non-metal Silver The color for Silver is Silver, the symbol for silver is Ag. The classification for Silver is Transition Metal; the atomic number for Silver is 47. Crystal Structure for Silver Is Cubic. The date that Silver was discovered is unknown and who discovered it unknown. The First energy level is 2.the second level is 8.Third energy level is 18, the fourth energy level the same 18.Lastly the fifth energy level is one.

Carbon can also exist in an amorphous state. Many allotropes commonly described as amorphous, however, such as glassy carbon, soot, or carbon black usually have enough structure to not be truly amorphous. Sulfur notes Sulfur is a pale yellow, odorless and brittle material. It displays three allotropic forms: orthorhombic, monoclinic and amorphous. The orthorhombic form is the most stable form of sulfur. Monoclinic sulfur exists between the temperatures of 96°C and 119°C and reverts back to the orthorhombic form when cooled. Amorphous sulfur is formed when molten sulfur is quickly cooled. Amorphous sulfur is soft and elastic and eventually reverts back to the orthorhombic form. Zinc notes Although zinc compounds have been used for at least 2,500 years in the production of brass, zinc wasn't recognized as a distinct element until much later. Metallic zinc was first produced in India sometime in the 1400s by heating the mineral calamine with wool. Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate Article posted May 19, 2012 at 04:04 AM GMT • comment • Reads 88

Titanium was discovered by William Gregor in the year 1791, but it was until 1910 that Titanium was able to be separated from the compound materials. Titanium is in lots of stuff like paint, rubber, paper, and many others. The color of Titanium is dark gray metal. The electronic configuration is [Ar] 3d2 4s2. Francium Francium is an element in millions of elements there is out there in the world. The atomic number for Francium is 87. The symbol is Fr. Francium was discovered by Marguerite Perey on 1939 in France also it was named after France. The electonic configuration for Francium is [Rn] 7s1. Where can you find Francium? Scientists estimate that there is no more than one ounce of francium in the earth's crust at each time. Since there is so little naturally occurring on earth, scientists must make francium so they will be able to study it. Yttrium My last element is Yttrium. The symbol for Yttrium is Y. The atomic number for Yttrium is 39. Johan Galodolin discovered it 1794. Yttrium was named after Ytterby, a village in Sweden. The electronic configuration for Yttrium is [Kr] 4d1 5s2. You can found Yttrium in minerals like monazite, xenotime and more. It’s combined whit europium to make the color red in TV’s. Where can you find Yttrium? Yttrium is found in oxide in rare earth minerals such as monazite and bastnasite. In the Solar System Yttrium was created by stellar nucleosynthesis.

Helium’s symbol is HE and the atomic number is 2 the melting point is 4.002602 the boiling point is -268.6°C. Helium is colorless. Sir William Ramsey discovered Helium in 1895. Helium was formed though the radioactive decay Uranium and Thorium. Helium is also used in cryogenics Now im going to tell you about my second element and that’s Nitrogen. I choose Nitrogen because it IS made out of ice cream and I love ice cream. Nitrogen’s symbol is N the atomic number is 7 the melting point is -209.9°C the boiling point is -195.8°C. Nitrogen is colorless Daniel Rutherford in 1772. My Third element is Neon. I choose Neon because I heard that we used it for the open signs in barber shops and that if u turned it on it would stay on for years until it burns out. Neon’s symbol is NE the atomic number is 10 the melting point is-284.6°C the boiling point is-246.1°C Neon is colorless. Sir William Ramsay discovered Neon in 1898 I hope you learned from this and you think of doing it to! Helium Symbol: HE Atomic number: 2 Melting point: 4.002602 Boiling point: -268.6°C Number of neutrons: 2 Classification: Noble gas Color: colorless Who discovered helium?: Sir William Ramsay When it was discovered?: 1895 Where it can be found?: What is it used for?: Helium was formed though the radioactive decay of the heavy isotopes Uranium- 238 , Uranium- 235 and Thorium -232. Uranium-238 is the most common isotope. Helium is also used in cryogenics Nitrogen Symbol: N Atomic number: 7 Melting point:-209.9°C Boiling point:-195.8°C Number of neutrons: 7 Classification: non metal Color: colorless Who discovered nitrogen?: Daniel Rutherford When it was discovered?: 1772 Where it can be found?: Nitrogen can be found in ice cream NEON Symbol: NE Atomic number: 10 Melting point:-248.6°C Boiling point: -246.1°C Number of neutrons: 10 Classification: NOBLE GAS Color: colorless Who discovered Neon?: Sir William Ramsay When it was discovered?: 1898 Article posted May 18, 2012 at 03:22 PM GMT • comment • Reads 370
 Article posted May 18, 2012 at 02:55 PM GMT • comment • Reads 38 Today, I am going to talk about my three elements I picked. My first element I picked was Neon. The symbol is Ne. Do you know what the atomic number to Neon is? It is number 10. Sir William Ramsay and Morris William Travers created/ found Neon in 1898. Neon can be found in tiny groups in the atmosphere. Also it can be found in the rocks in Earth’s crust. Neon gas is used for advertising signs. My next element is Potassium. The symbol for Potassium is K. The atomic number is 19. Sir Humphrey Davy found this element in 1807. You can find Potassium in minerals. The Potassium iron is very important to the muscle tissue. “K” is used for making glass and soap. My last element is Yttrium. The symbol is Y. The atomic number is 39. Did you know that Johan Gadolin found Yttrium in 1794? You can also find “Y” in minerals just like Potassium! It is used for red phosphors in the TV also, it is in radars. Thank you!! Article posted May 18, 2012 at 02:55 PM GMT • comment • Reads 38

Also I’m going to tell you how the three elements were discovered and what the symbol, and when it was discovered. Neon: Neon was discovered in 1898 by Sir William Ramsay. Neon is the second lightest inert gas. Neon’s atomic weight is 20.1797 and atomic number 10. The symbol for neon is NE. Neon is also a bright light that is on signs and glow sticks. Hydrogen: In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance and in the 18th century. Hydrogen is the chemical element with atomic number one. Hydrogen is the lightest element. The symbol for hydrogen is H. Hydrogen is gas that goes into your car. Helium: Helium is the chemical element with atomic number two and an atomic weight of 4.002602. On Earth it is relatively rare 0.00052% by volume in the atmosphere. The symbol for helium is HE. If you inhale helium your voice will change funny. I picked Neon, Hydrogen, and Helium because I think they were easy to do. Also they looked interesting to me. Thanks for reading and I hoped you liked it! Article posted May 17, 2012 at 03:03 PM GMT • comment • Reads 1514
