  • It's a colorless gas.

Chemical Properties of Hydrogen

  • Hydrogen is a highly flammable gas.
  • It has a reactivity to carbon, oxygen, nitrogen, and phosphorus.

Identifying Information on Hydrogen.

  • Its atomic number is 1.
  • Its mas number is 1.008.
  • It has 1 proton, no neutrons, and 1 electron.
  • Its location on the periodic table is in group 1, period 1.

The history and discovery of Hydrogen.

It was discovered in 1766 by an English man named Henry Cavendish by mixing hydrochloric acid with zinc.

Uses and applications of Hydrogen.

  • Hydrogen is the essential element for life.
  • It's isotopes are Protium, Deuterium, and Tritium.
  • It has many compounds such as Water (H2,O), Hydrogen Peroxide (H2,O2), Ammonia (N,H3), Methane (C,H4), Glucose Sugar (C6,H2,O6) and Sucrose Sugar, table sugar, (C12, H22, O11), etc..
  • Hydrogen bombs have been made and tested already. Hydrogen bombs use the nuclear fission from hydrogen's isotopes. They use the isotopes left over energy from when the isotopes were used for nuclear fusion. The hydrogen bombs are very volatile and highly explosive.

Fun facts about Hydrogen.

  • Hydrogen's name comes from Greek origin of Hydro (Water) and Genes (Forming).
  • Over 90% of all atoms in the universe are hydrogen.
