Germanium

electrical conductivity. Copper is used to conduct heat and electricity, and for currency. Another natural resource in southeast asia is tin. Tin is a chemical element with the symbol Sn and atomic number 50. Tin shows a chemical similarity to both germanium and lead. Tin is used to make cans if something comes in a metal tin it is most likely to be made out of tin. I think this might not be very useful because i don't think we can heat it up enough to get it to melt. Since we are on…

Space Programs to Venus My science fiction assignment will be about humans preparing to travel to Venus. In this paper, I wall talk about the Soviet Venera 9 mission. My science fiction paper will consist of ways for probes to survive on Venus long enough to work and restore Venus to what it is believed it was: an Earth-like planet. It will talk about the silicon carbide transistors which can withstand the extreme heat, nuclear batteries that can work on Venus as an alternative to solar and…

Beta-decay spectroscopy of the neutron-rich rare-earth nuclei Introduction Neutron-rich nuclei in rare-earth region are the most collective nuclei in nature since their protons and neutrons are lying far away from the shell closure limit, which proton shell closure are Z=50 and Z=82, and neutron shell closure are N=82 and N=126[1]. For example, the doubly mid-shell nucleus 170Dy[1] which has proton number Z=66 and neutron number N=104 is considered as the most collective in that region. Until…

Adolf Hitler It doesn’t a matter if the leader is bad or good in person but the leadership was good or bad. Several leaders passed away and today they are history but few of them are still alive due to their leadership skills, achievements, movements and remarkable actions. One of the famous commander and leader in history, Adolf Hitler was born in Austria and raised up in Linz. He moved to Germany in 1931 and then joined the German workers party, forerunner of the NSDAP in 1921. He attempted a…

Chemistry ERT - ITEM 3 Item 3.1 and 3.2 – Graphs The trend for the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is…

authorized in 1962. This computer was unlike anything seen before; it was ten times faster then any other computer built. There were many different changes in to the make the supercomputer so much faster and smarter. They changed their transistors from germanium to silicon. At this point they still struggled with the problem of over heating. The supercomputer was still a major break through and opened an entire different field for computer developments. Now with these massive computers capable…

scientist to come up with a periodic trend to predict the properties of elements which were not discovered at that time. Therefore, Mendeleev’s periodic table had empty spaces/gaps, so that these elements, once found can be then included. Gallium and Germanium were two such elements. Also in some cases, Mendeleev didn’t strictly follow the rule of ordering…

Robert Crowley Mr. Scott Period 3 October 30th 2015 Chemistry Introduction and Overview Elements are the substances that make up everything in the universe, known and unknown. This means that elements are what make up matter, and everything you see, hear and touch. There are 118 elements known to man, some that you may know include gold, iron and oxygen. Each of these have distinguishing qualities and they come in 3 different states of matter, solid, liquid and gas. Some of these are…

History of the periodic table of elements The periodic table of elements is an organized table of all chemical elements identified and recognized. Most forms of the table commonly include information such as each element’s atomic number, chemical properties, and electron configuration. Prior to the periodic table, the elements were arranged in groups of three called triads. These triads were created by Johann Dobereiner, a German chemist, in 1829. Dobereiner arranged these elements in groups of…
