Daily 40 no. – 12 Sir Humphrey Davy Daily 40 Hall of Fame! Congratulations to these writers! Davy (1778-1829) was a British chemist and an inventor. He is best known for his discovery of sodium, calcium, potassium, barium, boron, and magnesium. He invented the Davy lamp, which enabled miners to use it in gas filled mines. He also worked with electrolysis which led him to many of his discoveries. -- Julia Sir Humphrey Davy (1778-1829) a British chemist, best known to be the father of electrolysis. Electrolysis is the process of electricity decomposing elements; with electrolysis he had discovered several alkaline earth metals, alkali metals, chlorine and salt. He also suggested that acid contained replaceable hydrogen, which was replaced by metals. --Denise Sir Humphrey Davy, an English chemist from 1778-1829, was the first to use electrolysis to isolate potassium, sodium, magnesium, calcium, strontium and barium. He also discovered boron and recognized chlorine and iodine as two elements. He analyzed many pigments and proved that diamond is a form of carbon. --Isaac Sir Humphrey Davy (1778-1829) was a British chemist and inventor. He discovered some alkali and alkali earth metals and helped discover chlorine and iodine. He was the first to state that atoms are held together by electrical forces and used electrolysis. He also invented the Davy lamp. --Alanna Sir Humphrey Davy was a British chemist. He discovered that atoms were held together by electrical forces and that electricity could decompose compounds through electrolysis. By decomposing compounds, he discovered Na, K, Mg, Ba, B, and Ca. he also discovered and promoted the use of NO2, laughing gas. --Andrew British chemist Humphrey Davy (1778-1829) used electrolysis to divide compounds into their different elements; by doing so, he discovered sodium, potassium, calcium, magnesium, boron, and barium. Davy also named the element chlorine, studied acids and bases, and invented the Davy lamp, a safety lamp used in coal mines. --Chantal The chemist Sir Humphrey Davy lived in England from 1778-1829. Having broken down compounds with electric currents, he believed that atoms were electrically held together. Through this, he discovered potassium, magnesium, calcium, strontium, chlorine, and barium. In addition, Davy is famous for discovering nitrous oxide, or laughing gas. --Christine Born in 1778 Britain, Sir Humphrey Davy discovered many new elements (sodium, potassium, etc.) by using electrolysis to separate compounds. He also proposed that atoms were held together by electrical forces, leading to our modern understanding of atomic structure. He also experimented with nitrous oxide and discovered its anesthetic effects. --Dawy Sir Humphrey Davy (1778-1829) found that electric current could break down chemical compounds so he thought that atoms have positive or negative charge or they electrically connected together. He discovered metallic elements such as potassium, calcium, and sodium. He also found chlorine and laughing gas. -- Dee Dee Daily 40 no. – 12 Sir Humphrey Davy Sir Humphrey Davy, a British chemist, lived from 1778 to 1829 and discovered that atoms are held together by electrical forces. This showed how the parts of an atom hold it together. Also, he discovered many alkali and alkaline earth metals to add onto the periodic table. --Eric Sir Humphrey Davy was born on December 17, 1778 in England and died on May 29, 1829 in Switzerland. He discovered electrolysis, a process that decomposed compounds by running electricity through them, as well as a much of the alkaline earth metals, including potassium and sodium. --Eyad Sir Humphrey Davy (1778-1829) was a great British inventor and chemist, who is probably best remembered for his discoveries of sodium, potassium, magnesium, and many more. He invented the Davy lamp and was a pioneer in the field of electrolysis. --Gennelle Sir Humphrey Davy(1778-1829) was a British chemist. He discovered several new elements, was an electrolysis pioneer, and classified chlorine. He discovered sodium, potassium, calcium, magnesium, barium, and boron through electrolysis and proved that chlorine was elemental. Davy contributed to the periodic table by discovering several new elements and electrolysis. --Jaya Sir Humphrey Davy (1778 –1829), a British chemist, discovered many alkaline metals, like Potassium. Davy worked with electricity and discovered that running the current through compounds splits them into elements (electrolysis), which he used to discover some elements. Davy also promoted the use of nitrous oxide, or laughing gas. --Jeff Humphrey Davy (1778-1829) was a British chemist who discovered some of the alkaline and alkaline earth metals. He discovered these metals after he found out that electricity decomposes certain compounds and he called this electrolysis. So when he conducted electricity through sodium hydroxide, sodium clumps formed. --Karen Humphrey Davy was a British scientist who lived from 1778 to 1829. He invented the Davy Lamp, which could safely light gas mines. He discovered several alkali and alkali earth metals, including sodium and potassium. He studied electrolysis and learned that atoms were held together with electrical pulls. --Katy Sir Humphrey Davy (1778–1829) was a pioneer in the new field of electrochemistry and was very reckless in his experiments. He had discovered that some metals would decompose when electricity ran through it called electrolysis. He had discovered the elements potassium, sodium, magnesium, calcium, strontium, and barium. --Tatiana British chemist and inventor, Sir Humphrey Davy followed in the footsteps of Antoine Lavoisier and decomposed elements by running electric current through some of the substances. He called this process electrolysis. As Davy broke down these compounds, he understood that atoms within the elements were held together by electric forces. --Tokunbo Sir Humphrey Davy was an 18th/19th century British chemist and inventor. He developed electrolysis as a means of electrically decomposing compounds thus hypothesized that atoms are held together by electrical forces. Using electrolysis he isolated several alkali and alkaline earth medals such as: sodium, potassium, magnesium, barium, boron, and strontium. --Victoria .
