Best-known for his work in modern atomic theory, John Dalton was an English chemist, meteorologist and physicist. The son of a weaver, Dalton's major contribution to the field of chemistry is his atomic theory proposed in 1803. In the theory he reasoned that tiny particles called atoms make up elements.
We have all done litmus tests at school. How many of us know that Robert Boyle is the inventor of the litmus test. Considered to be the founder of modern chemistry, Robert Boyle was a scientist of the 17th century. Boyle is remembered for his law about the relationship between pressure and volume of gasses.
Sir Humphry Davy was an electrochemist who discovered several alkalis. He discovered elements like chlorine and iodine Davy is also remembered for brightening the lives of miners by making the miners safety lamp, now called the Davy lamp.
Sir William Ramsay was the Scottish scientist who discovered the noble gases. These gases are argon, neon, krypton and xenon. These gases along with helium and radon formed a new set of elements. For this discovery, Ramsay was awarded the Noble Prize in 1904.
Svante Arrhenius was one of the first chemists in the field of physical chemistry. He was the first person to discover the effect of global warming. His experiments focus on the effect of the doubling of the amount of carbon dioxide gas on the environment. Even today the issue of global warming is still debated and extensive research is conducted in this field.
