In 1940, Ed McMillan created the first artificial element - Neptunium. Over the 25 years Glenn Seabory, of the University of California at Berkeleydiscovered an entire family of new elements, 94 to 102.

The law of conservation of mass relates to chemistry because it requires a careful measurements and quantitative observations. Later, Jan Baptist Van Helmont suggested that there are other substances other than air and gave them the name “gas.” Gas originated from the Greek word “chaos,” and was soon used commonly amongst scientist. Van Helmont conducted several experiments involving gases. He is mostly remembered today for his ideas on spontaneous generation, his five year tree experiment, and also being considered the founder of pneumatic chemistry. In 1702 Georg Stahl came up with the name phlogiston to refer to the substance released in the process of burning.

His name was Mendeleyev, and he was a renowned teacher. Because no good textbook in chemistry was available at the time, he wrote the two-volume Principles of Chemistry (1868-1870), which later became a classic. During the writing of this book, Mendeleyev tried to classify the elements according to their chemical properties. In 1871 he published an improved version of the periodic table, in which he left gaps for elements that were not yet known. His chart and theories gained acceptance by the scientific world when three elements he "predicted"—gallium, germanium, and scandium—were subsequently discovered In 1856 another important figure in atomic theory was born: Sir Joseph John Thomson.
In the 1700’s, Antoine Lavoiser wrote the first extensive list of elements and categorized them into metals and non-metals . Johann Wolfgang Döbereiner and Alexandre-Emile Béguyer de Chancourtois also tried to classify the elements in the mid 1800’s but were not extremely successful. Döbereiner classified elements into triads with elements with similar properties while Béguyer de Chancourtoiswas the first to notice that when elements are arranged by their atomic weights, groups of elements ... ... middle of paper ... ...he same regardless of the type of atom. He then concluded that atoms consist of tiny, negatively charged particles. He, like Chadwick, received a Nobel prize for his work in 1906 .

The following picture demonstrates these effects. Originally, the inventors of the interferometer produced it to measure the speed of light so they could determine the existence of ether. Since then it has been important in measuring the wavelengths of light, using the wavelengths of light to measure very small distances (up to 0.5 microns), to measure extremely small times (up to 1x10-15 seconds), and to study optical media. Albert A. Michelson (1852-1931) The Michelson interferometer was invented by American Physicist Albert A. Michelson in 1887. Michelson was born in Strzelno (Poland) in 1852 and moved to American in 1855.
