Recommended: Periodic table and its analysis

The Periodic Table, its Sections and its elements The Periodic table was created by Dmitri Mendeleev, in 1869. It was developed to show people each element and its properties (physical or chemical). The properties of the periodic table is to show or predict the features properties that each element has. There are currently 118 elements that are on the periodic table, increasing by 1 from 2014 which was 117. Within the periodic table there are some regions, which include;The Alkali Metals, Alkaline Earth Metals, Rare Earth Metals, Transition Metals, Post-Transition Metals(other metals), Metalloids, Nonmetals, Halogens and Noble Gases. The oldest elements are; copper that was discovered in 9000 BC and Lead that was discovered in 7000 BC. First lets start with the nonmetals. Nonmetals are not elements that are able to produce electricity or heat very well, they are the most important elements on the periodic table though. They include 6 elements which are; Carbon, Nitrogen, Oxygen, Phosphorus, Sulfur, Selenium. Without some of them we wouldn’t survive, lets take oxygen for example. Without it we …show more content…

There are about 38 elements on the transition metals’ group. The elements are; Scandium, Titanium, Vanadium, Chromium, Manganese, Ruthenium, Cobalt, Rutherfordium, Copper, Zinc, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Iron, Rhodium, Palladium, Silver, Cadmium, Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Nickel, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Ununnilium, Unununium, Ununbium. Just three elements of this category are able to form a magnetic field. The elements are; Iron, Nickel and Cobalt. The most expensive and precious of all is Rhodium. It costs 100 times more than gold and 150 times more than silver which is actually a pretty high number for such an element. All of the transition metal elements can also conduct electricity and are

    Primo Levi’s personal relationship to his profession as a chemist shows that philosophically and psychologically, he is deeply invested in it. His book THe PeriOdic TaBLe shows that his methodology cannot be classified as either purely objective or purely subjective. He fits into the definition of dynamic objectivity given by Evelyn Fox Keller in her book Reflections on Gender and Science.

  • Mendeleev's First Periodic Table

    498 Words  | 1 Pages

    Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted

    Baking soda is made out of sodium, carbon, and 2 oxygens while vinegar is made up of 4 hydrogens, 3 carbons, and 2 oxygens. These elements are on the periodic table in their columns and rows, but how did they get there? Well the periodic table is arranged in rows, called periods, that tell you how many electron rings an atom has, it also has groups, horizontal columns, that tell you how many valence electrons, or electrons on the outermost layer, an atom has. The periodic table also shows you how many electrons the said element has. If you saw carbon on the periodic table then you would see that it has the atomic number above it, then it has the chemical symbol, its element name and then its ato...

  • Lead: The Most Important To The Structure And Chemical Properties Of Lead

    723 Words  | 2 Pages

    Lead is commonly referred to as Pb due to its chemical symbol on the periodic table (7). The Element as has an atomic number of 82 (7). From its atomic number, scientists can conclude that a natural element of lead contains a total of 82 protons, and 82 electrons (8). Lead also has an atomic mass of 207.2 (7). Being that the atomic mass is the number of protons plus the number of neutrons, scientists concludes that an atom of lead contains 125 neutrons along with the 82 protons (8). Lead is considered a poor metal on the periodic table. Lead is also in the p block of elements which means that its valence electrons will be in a p shell (8). Overall, the periodic table is a prime way to learn about the basics of

Depicting his childhood in the introduction, Sam tells the story of Mercury of how a single element connects to history, medicine, and even science. Although the periodic table is around us all the time Sam emphasizes the lack of teaching during his highschool career.

Pure radium metal is bright white when freshly prepared, but blackens once it is exposure to air. Radium has been used to produce neutron sources, luminous paints, and medical radioisotopes. Marie Curie is known to be the mother of science, due to Marie several discoveries, Mrs. Curie made up most of the Earth metals in the periodic table. Marie discovered Radium and other key elements, which help us in our daily lives, especially taking x-rays.

    The Periodic Table is based around the Atomic Theory. Firstly people believed that everything was made up the four elements Earth, Fire, Wind, and Water. This theory evolved into everything being made up of atoms. Breakthroughs throughout history such as the discoveries of the nucleus, protons, neutrons and electrons have pushed this theory forward to where it is today.

    The unique set of elements known as the alkaline earth metals are key components to humanity and life as we know it. Without them, many things that we both love and need would be gone. These remarkably diverse yet very similar elements that make up the alkaline earth metals family are: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). Although this family is often overshadowed by the infamous alkali metals, you will soon learn how spectacular and brilliant these metals really are and their value to human life.

  • The Physics of an Electric Motor

    A conductive atom’s valance shell is not completely full; electrons will flow from atom to atom because of this. When these electrons move from one atom to another, that is electrical current (a brief description of that is). A magnet can be made from different materials, but a loadstone is the natural form. The most important part of magnetism to make electric motors work is: A magnet has two different ends, or poles, a north and a south pole. These poles behave like electric charges, like poles repel and unlike poles attract although magnets have no effect on still charges.

Antoine Lavoisier and Dalton are responsible for the discovery of 90 natural elements. Dalton also explained the variations of water vapor in the atmosphere, the basis of meteorology. Dalton’s atomic theory says that each element contains its own number of atoms. Each element has its own size and weight.

    Then both Meyer and Mendeleyev built periodic tables alone, Meyer more impressed by the periodicity of physical properties, while Mendeleyev was more interested in the chemical properties. Then Mendeleyev had published his periodic table and his law in 1869 and forecasted the properties of the missing elements, and chemists then began to be grateful for it when the discovery of elements was predicted by the table that had taken place. Although, periodic tables have always been related to the way scientists thought about the shape and structure of the atom, and has changed over the years exactly for that reason.
