DEVELOPMENT OF THE PERIODIC TABLE Although Dmitri Mendeleev is often considered the "father" of the periodic table‚ the work of many scientists contributed to its present form. Elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known since earliest times. In 1649 the first scientific discovery of an element occurred. Hennig Brand‚ a German chemist‚ treated urine to a series of processes that resulted in the production of the element phosphorus. Over the next 200 years

Development of the periodic table ➢ The elements in the periodic table have been arranged in the order of the number of protons (a.k.a. atomic number) The next significant stage in the development of the periodic table was discovered by came from John Newlands. He arranged the known elements in order of their atomic masses. He introduced the ‘law of octaves’ which meant that every eighth element had similar properties. As it didn’t work for all the known elements it was therefore dismissed

motionless on your tray. Are there forces acting on the cup? If so‚ how do they differ from the forces that would be acting on the cup if it sat on your kitchen table at home? Determine the Concept Yes‚ there are forces acting on it. They are the normal force of the table and the gravitational pull of Earth (weight). Because the cup is not accelerating relative to the ground‚ the forces are the same as those that would act on it if it was sitting on your table at home. 2 • You are passing another

Periodic Table Elements such as gold and silver have been known since the earliest times. In 1649‚ a German alchemist‚ Hennig Brand made the first scientific discovery of an element‚ phosphorous. In the next 200 years‚ knowledge about the properties of elements and their compounds was gained. By 1869‚ 63 elements had been discovered in total. Scientists began to categorise those elements according to the similarities of their physical and chemical properties‚ which become the modern Period table we

The Process of Serving Tables The job of a server is more difficult than most people think. Many Americans love to dine at restaurants whether it’s to celebrate a special occasion‚ or just to save them the trouble of cooking dinner at home.

Joy Jenkins Changing of the periodic table Today‚ the periodic table organizes the elements in horizontal rows‚ or periods‚ by order of increasing atomic number. The elements are also organized in vertical columns‚ or groups‚ based on similar physical characteristics and chemical behavior. I believe the periodic table will continue to evolve as new elements are discovered. One of the earliest attempts to organize the elements based on their chemical and physical properties was made by German
