Element Baby Book Project due: January 21‚ 2013 In this project you will adopt an element from the periodic table. The element that you choose must have an atomic number from 1- 96. As a proud parent of your element you will create a baby book to remember each stage of your elements life. This project will count a TWO lab grades in science lab (200 pts total). Sources of Information: The periodic table in your book which you can access online Encyclopedia http://periodic.lanl.gov/index

Friedrich Ernst Dorn‚ and Glenn Seaborg. Stanislao Cannizzaro‚ born in 1826 and died in 1910‚ was an Italian chemist. He presented a method to measure atomic masses and to interpret the results of the measurements. Cannizzaro’s method aided scientists into agreeing standard values for atomic masses. The scientists then searched for relationships among atomic masses and other properties of the elements. Dmitri Mendeleev‚ born in 1834‚ was a Russian chemist‚ and is sometimes considered as the ‘father

Chemistry Henry Moseley Henry Moseley was a very accomplished British physicist. Henry was born in Weymouth Dorset‚ off the coast of southwestern England. Of his many great accomplishments he is generally known for sorting the periodic table by atomic number. Henry is important because of his work with atoms and the use of x-rays to study them. Moseley was a very bright scientist during the 19th century and his work helps even chemist today. Henry was born into a rather wealthy family and his mother

connection. His discoveries introduced atomic physics. He found out that the number of neutrons are not always the same. One thing led to another and the discoveries of Heisenberg helped to create the nuclear bomb. Henry Moseley Henry Moseley’s findings allowed for a more accurate placement for elements on the periodic table. He used x-ray spectra to study atomic structures to do this. Because of Mosley’s discoveries‚ the periodic table is ordered by an element’s atomic

Scandium is an element on the periodic table. Its atomic number is 21. Its atomic symbol is Sc. It has a silvery white color. It is classified as a metallic. Its group on the periodic table is 3. Its atomic mass is 45. Its melting point is 1541 Celsius. Its boiling point is 2836 Celsius. Its atomic is 216 pm. These a really interesting element. Scandium was discovered in Scandinavia in 1878. It was discovered by a man named Nilson. There is two metals that scandium has that were only found in Scandinavia

so unstable that there is no point trying to synthesis new elements? This leads to the question: ‘How does the size of an element affect the stability?’ What are superheavy elements? The scientific term ‘superheavy’ means elements that have an atomic number that is heavier than‚ element 101‚ which is Rutherfordium. As they suffer from radioactive decay when exposed to lighter elements‚ they are not naturally occurring. Meaning‚ scientists can only artificially make them in laboratories. [1][3] Explanation-

abundances in the environment. It is quite metallic in nature despite its location beneath oxygen in the periodic table. It is made in very small quantities through a nuclear reaction of bismuth. Neutron irradiation of 209bismuth (atomic number 83) gives 210polonium (atomic number 84). 209Bi + 1n ¨ 210Po + e- Polonium-210‚ 210Po‚ transmutes into the lead isotope 206Pb by the emission of an ¿-particle. The half-life for this process is just over 138 days meaning that after 138 days one-half of the original
