2. Hydrogen Background Discovered in 1766 by Henry Cavendish Name means: to generate water First element on the periodic table Most abundant element in the universe! Used in many reactions to make energy

3. Periodic Table Information Symbol: H Atomic #: 1 Atomic Mass: 1.008 Protons: 1 Electrons: 1 Neutrons: 0 Classification: Non-metal Configuration: 1s 1

4. Where its found and in what form Hydrogen is found in almost everything in the universe! From the sun to water hydrogen is in nearly everything. That makes it the most abundant element in the universe. Hydrogen is found at a Gas at room temperature, not liquid like some would think.

6. Uses Hydrogen is used in the production of ammonia Used in hydrogenation, which means hydrogen is added to unsaturated oil to keep fat from becoming old and stale Used in metal refining, removing unwanted elements Liquid hydrogen is used as fuel for rockets that have sent Space Shuttles into space Hydrogen is also used in hydrogen powered cars and
