HISTORY:- DISCOVERY OF INDIA BY JAWAHARLAL NEHRU INTRODUCTION:- The Discovery of India was written by India’s first Prime Minister Jawaharlal Nehru during his imprisonment in 1942-1946 at Ahmednagar in the Ahmednagar Fort. Nehru was jailed for his participation in the Quit India movement along with other Indian leaders‚ and he used this time to write down his thoughts and knowledge about India’s history. The book is widely regarded as a classic in India since its first publication in 1946

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

Lesson 3.01: History of the Periodic Table 1. Explain how scientific observations led to the development of‚ and changes to‚ the periodic table. Dmitri Mendeleev- first periodic table‚ organized 63 known elements according to properties‚ organized into rows and columns. He wrote names‚ mass and chemical properties on each. Julius lothar Meyer- independently worked in German ‚ similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals‚ he found that

The development of 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

Promethium‚ Pm‚ is the 61st element on the Periodic Table. It was discovered in 1945 by Jacob A. Marinsky. It’s a metal‚ and named after the Greek God Prometheus. It is not naturally occurring‚ but can survive outside of a lab. Promethium has an atomic number of 61‚ which is the number of protons. Its atomic mass‚ protons+neutrons‚ is 145u. It is an isotope. This means that it has a different number of neutrons (84) than the number of electrons and protons (61). Every element changes states

Describe the general trend or patterns that you observed in the atomic radius as you go across the periodic table. (2 points) It looks like the atomic radius is bigger if the atomic number is small. This may be because of the decrease of the pull that the protons give the electrons the smaller the atomic number.2. In Part

The 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. Between 1817-1829‚ Johann Dobereiner began to group elements with similar properties in to groups of three or triads. This began when he noticed that the atomic weights of strontium (Sr) were halfway between Calcium (Ca) and Barium (Ba). He stated that nature contained triads of elements in which the middle element

It is good to be reminded of the damages prejudice can cause and just how powerful it is as a social force The film was outstanding for me. The portrayal and the flow of the story were good. Jaclyn Smith was very good as Florence Nightingale. And the film really showed the complete detail of Florence Nightingale’s
