Isotopes of Paperclipium Purpose: To determine the isotopic composition of the element‚ paperclipium. Background Information: Isotopes are atoms of the same element with the same proton number but different mass number; that is‚ the number of neutrons differ. Isotopes of the same element have the same electronic configuration as they have the same number of electrons. This accounts for the fact that their chemical properties are the same‚ as the react similarly. However‚ their physical properties

1896‚ when Antoine Henri Becquerel discovered radioactivity in Uranium. The next step came in 1902 when Marie and Pierre Curie isolated radioactive metal called Radium. In 1934‚ Enrico Fermi of Italy disintegrated heavy atoms by spraying them with neutrons. Unfortunately‚ he didn’t realize that he had achieved nuclear fission‚ In December 1938‚ Otto Hahn and Fritz Strassman in Berlin did a similar experiment with Uranium and were

Siilicon is the closely related elements with boron. Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron is used to control nuclear reactions. It is an excellent neutron absorber. Alloyed with steel or reacted with carbon‚ titanium or zirconium‚ it is used in control rods for nuclear reactors Boron is an essential nutrient for all green plants Bibliography: http://chemtopics.com/elements.htm http://www.webelements

Ruthenium is solid at room temperature and looks like a hard‚ silvery-white metal with a shiny surface ( See page 2 for picture. ).The 3 main types of subatomic particles are protons‚ neutrons‚ and electrons. To humans Ruthenium is highly toxic and carcinogenic‚ and shouldn’t be touched if came into contact with. Five fun facts about is one‚ Ruthenium was founded in 1844 by Karl Ernst Claus. Also‚ the metal is used as a hardener for

of the greatest wonders of modern science. It is a substitute for the human brain. In every sphere of life man has been using computer. The invention of nuclear energy is a great wonder of modem science. Now man can make Atom Bomb‚ Hydrogen Bomb‚ Neutron Bomb‚ Missiles etc. with the help of this energy. Space travel is the most wonderful success of modern science. To land on the moon was out of man’s imagination just a few years ago. Biopsy and Ultrasonography‚ E.C.G‚ Ultra-violet ray‚ X-ray and

(man-elements) are created‚ or why do we benefit in creating them? Elements are the building blocks of which all things are composed. The elements of Earth are made up of atoms. All atoms possess a nucleus of positively charged protons as wells and neutrons which are neutrally charged. Surrounding the nucleus is a low density area containing negatively charged electrons that are equal to the number of protons within the nucleus. The number of protons within an atom determines the element that it composes

We all are aware of the basic states of matter i.e. solids‚ liquids‚ gases‚and plasma. But apart from these there’s an entire range of alternative synthetic states of matter: Bose–Einstein condensate‚neutron degenerate matter‚ supersolids/superfluids‚ etc. The difference is that these alternative states are actually lab-synthesised and don’t have much significance in the real world of nature. And now‚ a team of researchers at Japan’s Tohoku University have claimed to synthesise an entirely new metal

Democritus 1 Democritus Democritus was a Greek Philosopher born 460 B.C. in the city of Abdera‚ and died 370 B.C. He was born into a wealthy family and traveled the world extensively. He was known as the “laughing” philosopher‚ or the “happy” philosopher because he would constantly mock people‚ and laugh incessantly about his own jibes. Throughout his life he wrote over 70 books‚ however very few pages have survived the years. Some have said that Democritus blinded himself to better understand

For a considerable length of time‚ researchers have been searching for purported "glueballs." Now it appears they have been found finally. A glueball is an extraordinary molecule‚ made up altogether of gluons - the "sticky" particles that keep atomic particles together. Glueballs are insecure and must be identified in a roundabout way‚ by investigating their rot. This rot process‚ then again‚ is not yet completely caught on. Teacher Anton Rebhan and Frederic Brünner from TU Wien (Vienna) have now

The History of the Atom Hypothesis according to Aristotle (350 BC): All matter consists of the elements earth‚ air‚ fire‚ and water. Experiment: A tree grows from the earth as water is added. The tree is then set on fire in an effort to form new elements. 1. What kind of results would be observed from this experiment? Fire‚ ash (earth)‚ smoke (air) 2. Would these observations support or reject the hypothesis? Explain. Support. No elements have been produced that are something other than
