Science Periodic Table Essay

The Periodic Table The periodic table has been updated both last(predicate) throughout history. Elements mystify been around us since the beginning of time. Elements, such as gold and silver, are examples of these elements that have been known for centuries. The periodic table allows us to see the elements in their families so we can understand what properties they have. It similarly allows us to see the atomic number, atomic mass, and the symbol of the element. The periodic table is a source of noesis that is still being updated as of this day.That is why the periodic table is such a valuable resource. In ancient times, the elements gold and silver were discovered. Another element that was known at this time was copper. The Greek philosopher, Aristotle state that all elements were made out of these four roots. The philosopher, Plato, renamed the four roots earth, fire, water, and air. Although they introduced the concept of elements, they did nothing to advance the record of the matter, which matter is made of. The age of enlightenment was a big adventure for the science world.Hennig Brand was the first-year person recorded to have discovered a new element. He was a German merchant who went bankrupt, while trying to discover the Philosophers Stone. The Philosophers stone was a mythical object that was suppositious to turn inexpensive base metals into gold. He experimented with distilling human urine until he finally obtained a snow-clad substance which he named phosphorous in 1649. Brand did not go to the public with his discovery until some other scientist named Robert Boyle rediscovered it and took it to the public.In 1661, Boyle defined an element has a substance that cannot be broken down by chemical means. Antoine Lavoisier genuine the first chemistry textbook. This included the elements oxygen, nitrogen, hydrogen, phosphorous, mercury, zinc, and sulfur. Lavoisiers descriptions of the elements only sort out elements as metals or non-metals. Johann Dobereiner began to classify the elements in triads. These elements that give-up the ghost to these triads had properties that were similar to separately other. A few of these triads are as follows 1.Chlorine, bromine, and iodine 2. Calcium, strontium, and barium 3. Sulfur, selenium, and tellurium 4. Lithium, sodium, and potassium. With all these triads, the atomic mass of the second element was almost exactly the average of the atomic weights of the first and third gear elements. By 1869, 69 elements had been discovered. Alexandre Chancourtois was the first to notice the periodicity of the elements. Similar elements seemed to occur at regular intervals when they were set up by their atomic mass. He created an early version of the periodic table.He called it the telluric helix. When the elements were arranged on a cylinder by order of the increasing atomic mass, Chancourtois could tell that the elements with similar properties lined up vertically. He print this work in 1 862, but there was little to go on. In 1865, John Newlands classified 56 elements that had been discovered previously into eleven groups based on similar physical properties. Newlands said that legion(predicate) pairs of similar elements existed differed by some multiple of eight in atomic number.Dimitri Mendeleev created the periodic table that we theatrical role today. He arranged the elements by their atomic mass and noticed that they lined up with the elements that had similar properties with each other. He also noticed that when they were arranged in this way, the valences lined up as well. When he published his table in 1869, it had many advantages. This table is more widely used in todays time. The discovery of the periodic table is also the discoveries of the elements.As the elements were discovered, they were added to the periodic table. Since the beginning of time, more elements have been discovered. The most novel was ununpentium. It was discovered in 2011. As anyone c an see the periodic table is continuing to grow and develop. It is a child of the elements. As each element is named, the periodic table grows. The periodic table will constantly be an ongoing process and the updating of it will never end. That is because new elements are discovered every day
