.About Humphry:*Born- December 17, 1778*Died- May 29, 1829*Discovered- Barium, Calcium, sodium,baron*Siblings- John Davy*Parents- Grace Millet, Robert Davy*Country- British

Humphry made a huge impact on the studies of science. One example of his impact is when he presented the decomposition by galvanism of the fixed alkalies. He performed a demonstration that these alkalies are simply metallic oxides. These discoveries are said to be the most important contribution made since Sir Isaac Newton.

Humphrey created nitrous oxide (laughing gas) his work lead to an appointment as chemical superintendent of the pneumatic institution. He explored areas like oxides, nitrogen and ommonia. Then he published his findings in the book Researches, Chemical, and Philosophical. He got recognized and then became a professor of chemistry at the Royal institution of Great Britain.

Barium, calcium, potassium, sodium, baron

Chemical bonding was electrical in nature and that he could use electricity to split substances into their basic building blocks.Facts:*Solid at room temperature*

Experiment Sodium and water

Received an early education. He was a naturally gifted and sharp boy who could write impressive fiction and poetry. He went attended Truro Grammer School.

* atomic number-56* atomic weight-137.327*melting point-1000k* classified as a metal* never found them for you later since it reacts with oxygen in the air.* barium sulfate is a common barium compound, used as a filler for rubber, plastics, and resins.* barium sulfate will glow when exposed to light glow in the dark for up to six years is intensely heated in the presence of charcoal.* all barium compounds are poisonous* does not dissolve in water

* alkali metal* atomic weight-22.98977* atomic number-11* very reactive* soft metal that can easily be cut with a knife* sixth most abundant element of earth* only found in compounds because it is so reactive.* primarily used in the form of compounds with other elements* can be found in table salt* helps maintain the proper fluid balance in the body's cells and helps us digest our food.* we lose sodium when we sweat

*Discovered in 1808* atomic weight-10.81* electrons-5* protons-5* solid at room temperature* discovered in France and England* originally called boracium* boron filaments are used with plastic metals or reinforcements to form composites

*atomic number-20*atomic weight-40.078*solid at room temperature* fifth most abundant element in the earths crust*easily forms compounds by reacting with oxygen and water.* A bout 4.2% of the Earth's crust is composed of calcium.* calcium is used to remove oxygen, Sulfur and carbon from certain alloys.* chalk marble and limestone are all forms of calcium carbonate.* calcium carbonate is used to make White paint, cleaning powder, stomach antacids, etc.

Calcium

*solid at room temperature *all living things need potassium to maintain fluid balance.*all forms of life need potassium minerals to survive*available in all meats, plants, and dairy products*potassium is made in the oxygen burning shell of stars when they explode.*people whose diets are low potassium can suffer from hypokalemia
