Analysis Of Henry Moseley's 'Completing The Table With A Bang'
1. What is the difference between a “dirty” bomb and a conventional nuclear bomb? (1 mark)
The difference between a “dirty” bomb and a conventional nuclear bomb is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and turns some cells into cancer cells. Though nuclear bombs also emit some radiation, it is not intentional that that occurs.
2. Summarize the life and work of Henry Moseley. (3 marks)
Throughout his life, Henry Moseley was buried in his studies, spending most of his time in the laboratory. With Darwin’s grandson, he researched how atoms behaved when they were struck by a beam …show more content…
Why didn't scientists at the University of California at Berkley call element 97 and 98, Universitium and Ofium, respectively? (1 mark)
Scientists at the University of California at Berkeley did not call elements 97 and 98 as ‘Universitium’ and ‘Ofium’ because they were worried that New Yorkers might name the next two ‘newium’ and ‘yorkium’, making the phrase “University of New York” rather than “University of California at Berkeley”.
4. Explain how some Russians think the wealth of minerals got to Russia. (1 mark)
Some Russians believe the myth that god made a mistake when assigning different minerals to different areas. They believe that god must have had a variety of elements with him when he visited the Earth, and decided to put Tantalum in one area, and uranium in another area. However, when he reached Siberia, his hands were too cold, which made him drop all of the elements. Then, God left Siberia without picking up the elements, as his fingers were too frozen to move. The Russians believe that the act of God dropping elements in Siberia is the reason for the wealth of minerals in
