The Disappearing Spoon by Sam Kean‚ examines each of the elements on the periodic table. The Disappearing Spoon focuses on the history of the periodic table by recounting stories about each element on the table‚ and the scientist that discovered it. For each element‚ Kean provides an extensive backstory about its origin‚ the common (or uncommon) uses of the element‚ and other interesting tidbits. The author begins the novel with a general physical description of the periodic table as a whole; he

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic

The 7 Most Common Metalloids Boron Silicon Germanium Arsenic Antimony Tellurium Polonium Their Uses: Boron -Amorphous boron is used in pyrotechnic flares to provide a distinctive green colour‚ and in rockets as an igniter. The most important compounds of boron are boric (or boracic) acid‚ widely used as a mild antiseptic‚ and borax which serves as a cleansing flux in welding and as a water softener in washing powders. Boron compounds are also extensively used in the manufacture of borosilicate

Question: “It is more important to discover new ways of thinking about what is already known than to discover new data or facts. To what extent would you agree with this claim?” According to the Miriam-Webster dictionary‚ data can be defined as factual information used as basis for reasoning‚ discussion‚ or calculation. By the same dictionary‚ fact is defined as a piece of information presented as having objective reality. In this essay‚ it is vital to distinguish that the issue the question

Seven years in isolation? I grew rather inquisitive as I read the book “The Fermat’s Last Theorem” by Simon Singh. ‘Sagely’‚ I thought‚ as I kept learning more about Professor Andrew Wiles through the course of the book. To spend time solving a believably unsolvable riddle in Mathematics is penance. He must have tormented himself to add a diamond to the mine or mountain of knowledge; but possibly the ecstasy at the end put all that at naught. That and the thought ignited in me‚ that burgeoning zeal

Chemical Periodicity Engr. Imelda Galera De La Salle University-Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT Chemical periodicity was demonstrated using different samples of elements from Group IA‚ IIA and IVA. These samples are: Li2CO3‚ Na2CO3‚ K2CO3‚ MgCO3‚ CaCO3‚ BaCO3‚ Carbon‚ Tin‚ Silicon and Lead. Each sample was placed in a test tube‚ (one sample and one test tube) and the physical color‚ appearance and state was defined. Water was used to test the solubility of the element

The element symbol for Germanium is Ge. It is located in row 4 column 4 on the periodic table and is in block p. It belongs in group 14. Germanium was first proposed by Dmitri Mendeleyev in 1871 based on the gaps found in the newly made periodic table. Germanium was first discovered by the German chemist Clemens Winkler ( Winkler ). Clemens Winkler was born in Freiburg‚ Germany in 1838 but he grew up Zschopenthal‚ Germany. His father Kurt Winkler was a well known chemist and metallurgist. Clemens
