Hydrogen

Hydrogen is the lightest element on the periodic table weighing 1.00794 u. It also is the most abundant resource in the universe it is in many non remnant stars. Hydrogen was artificially produced in the early 16th century.

Uses of Hydrogen

~Some uses are to clean fuel of the future, generated from water and returning to water when it is oxidized.

~In the glass industry hydrogen is used as a protective atmosphere for making flat glass sheets. In the electronics industry it is used as a flushing gas during the manufacture of silicon chips.

History of Hydrogen

In the early 1500s the alchemist Paracelsus noted that the bubbles given off when iron filings were added to sulfuric acid were flammable. In 1671 Robert Boyle made the same observation. Neither followed up their discovery of hydrogen, and so Henry Cavendish gets the credit. In 1766 he collected the bubbles and showed that they were different from other gases. He later showed that when hydrogen burns it forms water, thereby ending the belief that water was an element. The gas was given its name hydro-gen, meaning water-former.

Effects of Hydrogen on people


Exposure to high levels of hydrogen sulfide gas is a well-documented and understood hazard. OSHA and NIOSH standards have long recognized this acute risk with appropriate short-term maximum exposure levels for workers. However, long-term, chronic exposure to low levels of hydrogen sulfide is not as well understood.


Concentration Symptoms
0-10 ppm Irritation of eyes, nose, and throat.

2 ppm Bronchial constriction in asthmatic individuals, spontaneous abortion

5-9.3 ppm Increased blood lactate concentration, decreased skeletal muscle citrate synthase activity

10-50 ppm Headache, dizziness, nausea, vomiting, coughing, difficulty breathing

150-250 ppm Olfactory paralysis

50-200 ppm Severe respiratory tract irritation, eye irritation/acute conjunctivitis, shock, convulsions, coma and death in severe cases

Hydrogen Bomb!!!!

hydrogen bomb or H-Bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. And it makes a really big boom.
