Euclid's Elements

A atom is the basic unit of an element .it is a form of matter which cannot be broken down any further .an atom consist of sub atomic particles which are protons, neutrons and electrons .I will be looking at specifically the atom lead. Every element in the Periodic Table has been given a letter symbol , the symbol for lead is Pb.i will now describe the sub atomic particle in lead .protons are in the nucleus of the atom , All atoms of the same element have the same number of protons. This number…

An Isotope is an atom of an element which has a different number of neutrons and different mass number but the same proton number. The isotope that will be focused in the essay is carbon 14 isotope. Carbon is found in all living things and is the building block for organic material, there is carbon 12, 13 and 14 and they all have different properties. This isotope was discovered on February 27, 1940 by Martin Karmen and Sam Ruben and is the most radioactive out of all carbon isotopes. The…

physical and chemical properties of matter. Physical chemistry is the combination of chemistry and physics analysing the physical make up of chemical properties and the interactions between energy and matter. Organic chemistry, is heavily based on the element of carbon and its relation with life. Due to carbon’s complex and unique properties molecules that make up living tissue have carbon as an essential part of their composition, hence the given name of organic chemistry the “Chemistry of…

39, ‘Safe Handling of Plutonium’ ( IAEA, 1998). Plutonium is a man-made radioactive element that is made from uranium in nuclear reactors (Environmental Protection Agency, 2014). Much of the plutonium made was to be used for nuclear war. When plutonium decays it releases radiation. So do the other forms of isotopes. The half-live of these…

A Global Analysis Of Xylem Vessel Length In Woody Plants is a research paper published in the American Journal of Botany. Dr. Anna L. Jacobsen led the research efforts along with support from Dr. Pratt, Dr. Tobin, Dr. Hacke, and Dr. Ewers. The aims of their research were to explain the physiological role that xylem vessel length have on a plant 's hydraulic architecture. To effectively explain the relationship, researchers focused on a couple of key questions. First, they wanted to determine if…

Chlorine is an element that consists of 17 protons, an average of 18.5 neutrons and 17 electrons. It has an atomic number of 17, and an average nuclear charge of 35.5. There are 2 isotopes of chlorine that are 35Cl and 37Cl. 35Cl has an atomic mass of 35 and a natural abundance of 75%. 37Cl has an atomic mass of 37 and a natural abundance of 25%. The average atomic mass or nuclear charge equates to 35.5. Both of the isotopes have the same atomic number. (BBC Bitesize. Atoms and the periodic…

ISSUE Under Florida statutes and cases pertinent to inadvertent disclosure, is Mr. Beene required to return the privileged documents when (1) the products liability team inspected each document included in the discovery; (2) the amount of inadvertent disclosures was miniscule; (3) the degree of disclosure was rather small; (4) Mr. Fitzgerald requested the return as soon as he became aware; and (5) the client has a right to prevent disclosure of confidential communication, as well as an attorney…

FePO4 stands for Iron(III) Phosphate. Although α-FePO4 and β-FePO4 may sound quite similar as they may only differ in terms of the α and β, they β are actually very different in terms of the crystal structures and crystal chemistry of quartz. Based on the research article which was provided in coursera, it states that FePO4 is studied across a range of temperatures ; 294K to 1073K by neutron powder diffraction. The different range in temperature shows different structures. For instance, at…

“All animals are equal, but some animals are more equal than others.” This quote was written by George Orwell in his book Animal Farm, one of Orwell’s most famous novels. Throughout history the subject of a distant dystopia has always been explored in many works of literature. The possibility of humanity falling into a bleak and totalitarian society has always fascinated readers. These stories and themes can come to define an author and their legacy as a writer. There is no greater example of…

An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…
