1 Hydrogen By Jason Pynnonen

2 Important Terms Hydro=Water Genes=Generator Pauling Scale(electronegativity) Protium Deuterium (AKA Heavy Hydrogen) Tritium

3 Basic Information Atomic Number- 1. Atomic Weight- 1.00794 Makes up about 75% of the universe’s elemental mass. Nonmetal. Oxidation Numbers- (-1, 1) Hydrogen - Wikipedia, the free encyclopedia

4 Physical Properties Phase of matter- Gas Specific Heat Capacity- (25 degrees Celsius) Boiling point- (-423.17 Fahrenheit) Melting point- (-434.45 Fahrenheit) http://genchem.chem.wisc.edu/lab/PTL/ptl/Ele ments/H/H_Phys.html

5 Who/When/Where? Henry Cavendish 1766 London, England www.Webelements.com

6 How Was it discovered? Cavendish collected it after he created a reaction between Mercury and some acids. Hydro=Water Genes=Generator

7 Reactivity Very Reactive 3 Natural Isotopes – Protium – Deuterium (AKA Heavy Hydrogen) – Tritium http://science.jrank.org/pages/3455/Hydrogen- Reactions-hydrogen.html

8

9 Important Compounds H2O NH3 H2O2

10 Everyday Uses of Hydrogen and its Compounds Water Ammonia Hydrogen Peroxide Propane Methane

11 Characteristics Colorless Odorless Electronegativity(pauling scale) –(2.18) Structural shape- Hexagonal Very dangerous in some reactions with oxidants.

12 Advanced Hydrogen Uses Hydrogen Cars – Ford Fusion Hydrogen 999 Fuel Cell Race Car Blimps and Zepplins – Hindenburg accident

13 Quiz Questions 1. What does Genes mean in English? 2. What is the atomic weight I gave for Hydrogen? 3. What is the specific heat capacity for Hydrogen? 4. Who discovered Hydrogen? 5. When and where did he discover it? 6. What are the names of 2 of the 3 isotopes? 7. According to the chart I showed, what is the most reactive with hydrogen? 8. What is the most important compound? 9. What is hydrogens rating on the pauling scale? 10. How fast did the fastest hydrogen car go?
