Transcript of Hydrogen Chemistry Powerpoint

Periodic Table Info Element Name: Hydrogen
Symbol: H
Atomic Number: 1
Mass Number: 1 Discovered by Robert Boyle in 1671: iron and acids experimenting
Henry Cavendish 1766 accepted as element History Early Uses Transportation Charles and Robert's invented an aircraft, "hydrogen gas aerostat" in the 18th century. It was used for people to fly across the sky. Space In 1943, at Ohio State University, a rocket successfully launched with hydrogen as the fuel. Hydrogen soon became more favorable as a reliable fuel for rockets and launchers. Military German Ferdinand von Zeppelin invented airships, called zeppelins. He used flammable hydrogen gas which caused it to expand and fly. Later on, it was used in World War I for bombing and spying purposes, but then became discontinued due to defensive inability. Family/Group and Period Period Number: 1
Group Number: 1
Hydrogen does not have a family because it is a non-metal...so this element is very lonely at the top. Subatomic Particles Number of Protons: 1
Number of Neutrons: 0
Number of Electrons: 1 Properties/Characteristics Hydrogen By: Tammy Bui
Chemistry Honors
Period 1 State: solid, liquid, gas, vapor
At room temperature: Gas
Density: 0.00008988 g/cubic cm
Boiling Point: -252.87 degrees Celsius
Isotopes: 6 types - 3 most known & only are stable
1. Protium (simplest & stable)
2. Deuterium (found in 1932 & stable)
3. Tritium (1934)
Melting Point: -259.34 degrees Celsius
Highly reactive
Non-metal
Natural
Hydrogen alone is an acid, but with carbon dioxide, it is a base.
Crystal Structure: Hexagonal
Colorless, no odor, no taste Practical Uses Today 1. http://education.jlab.org/itselemental/ele001.html 2. http://www.hydrogen-planet.com/en/hydrogen-1/its-history-2/early-uses-of-hydrogen.html 3. http://www.ideafinder.com/history/inventors/zeppelin.htm 4. http://www.chem4kids.com/files/elem_alkalimetal.html 5. http://www.chemicalelements.com/elements/h.html 6.http://www.rsc.org/chemsoc/visualelements/pages/data/intro_hydrogen_data.htm Bibliography Environmental Hydrogen is used to extract sulfur from oil to clean and improve the fuel
With fuel cells, hydrogen can provide an efficient energy source for electric cars. 7. http://www.hydrogen-planet.com/en/hydrogen-1/its-uses.html Food/Drink With vegetable oil and other fats, hydrogen can make it become a margarine (butter). Weapons Hydrogen isotopes can also be used to make weapons. Nuclear reactors contain deuterium. Tritium is also used to make bombs. 8. http://www.wisegeek.org/what-are-some-uses-of-hydrogen.htm# Medicine Tritium plays an important role in nuclear medicine due to the increase of cancer diagnoses . This isotope is used for X-rays and its purpose is finding tumor markers. Location on Earth 9. http://www.ehow.com/list_6019214_medicinal-uses-hydrogen.html Because of the gravitational pull of Earth, most of hydrogen has left our atmosphere and is mostly found in outer space. However, the remaining of hydrogen on Earth is found in many places. Three quarters of Earth is covered by large bodies of water. Hydrogen is in many compounds like hydrocarbons (fossil fuel), hydrogen and carbon. Furthermore, hydrogen is a part of the Earth's crust and can be made through bacteria and algae (in gas form). Of course, hydrogen combined with oxygen, makes water, which is vital in every human's body to survive. 10.http://www.odec.ca/projects/2003/kaush3k/public_html/WhatHydrogen.htm 11. http://www.eoearth.org/article/Hydrogen#gen3 Fun Fact: Hydrogen is the lightest element on the periodic table.
