Stone Table

Scerri starts his book off by talking about a few people and describing what they did, and how they contributed to chemistry/periodic table. One person being John Dalton who developed what is known to be modern atomic theory. Another being…

book about the periodic table and how each element was discovered and how it affected each scientist when they discovered it. The story shows scientist such as Maria Goeppert, Dimitri Mendeleev, Robert Bunsen, Fritz Harbor, William Crookes, and many more. However, in this essay I am going to write about Dimitri Mendeleev, Robert Bunsen, and Fritz Haber. Dimitri Mendeleev is a very important scientist when it come to the periodic table, he is known as the, “creator” of the table. Mendeleev was…

Introduction: Dmitri Mendeleev is accredited with the creation of the periodic table but in reality, many scientists have contributed in the years leading up to the production. Before people could even write they knew some of the elements that are on the periodic table. The elements include silver, gold, copper, tin, lead, and mercury (substances that could not be broken down chemically). Not until 1649 did a man by the name of Hennig Brand discover phosphorous (an element) through…

Discovery and Organization of the Periodic Table In order to understand the periodic table, a basic knowledge in the terminology would be very helpful. A periodic table a chart organizing elements by atomic numbers and chemical properties into groups and periods. The periodic table was created in order to easily find and classify the different elements that are known. Elements are pure substances composed of just one type of atom that cannot be broken down into anything simpler by ordinary…

Alchemy was the earliest understanding of today’s chemistry. These two display Is Alchemy Chemistry? different pathways of thinking and rationalising rather than two diverse concepts. The practice of alchemy is the basis of chemistry, as it was a vital role of origin and evolution towards chemistry we know today. The comprehension of both alchemy and chemistry will aid in order to establish their connections and difference of opinion or belief. Discovering both histories of the two concepts will…

crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of metals and combine with other elements so easily that they are not found on earth in the form of…

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…
