The periodic table was the most important development in the field of chemistry. Do you agree?

The periodic table was the most important development in the field of chemistry and is the most important chemistry reference there is. The periodic table played a crucial part in the development in the field of chemistry as it allowed for a way of organising the elements so that it was possible to make predictions about both their chemical and physical properties based on the elements’ position in the table. The periodic table is grouped into many different divisions: Groups, Periods, Blocks, Metals, Metalloids and Non- Metals. It also allowed for many periodic trends to be identified. Because of the development of the periodic table, we are able to identify the electron configuration, the atomic radii and the ionisation energy, electronegativity and electron affinity as well as metallic character. Dmitri Mendeleev was the first person to fully develop a working periodic table which was very similar to the modern periodic table however many before him created a variety of different versions of the periodic table both before and after him.

One of the ways the periodic table is arranged is the arrangement of elements into groups. This is extremely useful as without these classification, we wouldn’t be able to identify similar trends in particular elements. A group is a vertical column in the periodic table and they are numbered from 1 to 18. It shows the number of electrons in the outer orbital. Elements in the same group usually tend to show patterns in the atomic radius, ionisation energy and electronegativity. The atomic radii of the elements increases from top to bottom in a group. Due to there being more filled energy levels, val...

...erties based on the elements’ position in the table. Trends in the periodic table such as groups, periods, blocks, metals metalloids and non-metals as well as trends between each grouping method would be difficult and almost impossible to identify without the existence of the periodic table. Also, periodic trends such as electron configuration, atomic radii ionisation energy, electronegativity, electron affinity and metallic character would not be identified without the discovery of the periodic table. Although the periodic table has minor flaws such as different elements not fitting in to some trends and more important discoveries such as the atomic theory and the synthesis of Urea were important to the field of chemistry, the periodic table is the foundation or the building blocks for further discoveries and so its development is important to the field of chemistry.

Essay about The Periodic Table Of Elements

- Abstract The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed....   [tags: Periodic table, Chemistry, Chemical element]

Similarities And Differences Of The Chemistry Field Essay

- ... Professor McConnell writes for about four hours a day or more when he has a major project he is working on. Before his work goes to the chemistry refereed journal the writing first has to go to the editor and they send it to reviewers. It then goes back to the editor who has the last say if the article will be put in the chemistry refereed journal or if it will be given back to the professor to make some changes. Professor Mc Connell said, “They mark all over my work and are straight to the point on the changes that should be made, which I feel that has helped me get better in my writing skills, even though they might be harsh on the comments.” A publication is consider to be an importa...   [tags: Scientific method, Chemistry, Science, Scientist]

What The Periodic Table Tells Us? Essay

- What the periodic table tells us. Why its discovery had taken up more than 50 years. Why is Mendeleev considered to be the ‘father’ of the Periodic Table. The periodic table is one of the most noticeable icons in chemistry. This table shows the organization of the elements in horizontal rows, called periods, and in vertical columns, called groups. It is an arrangement according to the increase of their atomic number in each element, which is equal with the number of the protons in the nucleus, and also based on similar chemical behavior and physical characteristics....   [tags: Periodic table, Chemical element, Chemistry]

The History of Chemistry Essay examples

- ... Michael Faraday discovered that a definite quality of change must flow in order to give weight in the solution. Avogrodro introduced the hypothesis that equal volumes of gases at the same pressure contain the same number of molecules. Prout thought that all elements have an atomic weight and multiples with the weight of hydrogen. This hypothesis contributes to the periodic table. The periodic table was independently found by J. L Meyer in Germany and D.I Mendeleev in Russia (1869). Adding on to that William Ramsay and Lord Rayliegh found other gases to extend the periodic table....   [tags: alchemy, the periodic table]

Essay on Physics : The Periodic Table

- The Periodic Table. The Periodic Table is an arrangement of the chemical elements and is one of the most important references for anyone doing chemistry. The elements on The Periodic Table are arranged according to their atomic number and their electronic configuration. The atomic number is listed next to the chemical symbol for the element in the top left corner. The atomic number can also be known as the Proton number of an element. The electron configuration of an atom is the representation the arrangement of electrons that are distributed among the orbital shells and subshells - http://chemwiki.ucdavis.edu/Inorganic_Chemistry/Electronic_Configurations There are two types of bonding in a...   [tags: Atom, Periodic table, Chemical element]

The History of the Elements and Periodic Table Essay

- Greek thinkers and early people noted around 400BC, that things are different from each other, and can be broken down into smaller groups. They used the words “element” and “atom” to describe different and the smallest parts of matter. For over 2000 years, the four “elements” of Earth, fire, water, and air were used to explain many stories of the world. Something had to of been done to organize our thoughts and observations of our elements. A method was needed by 1860 to organize the sixty elements known by scientists....   [tags: Chemistry, Science, research papers]

Cramming vs. Periodic Studying Essay

- One of the most stressful aspects of high school and ultimately college is the ability (or lack thereof) to form good study habits. One may often hear the dramatic tale of a college student staying up all night in order to receive a good grade on his or her test the following morning. This student either completely fails the test, or does really well. These results depend on the students themselves and their ability to study in this manner. In this essay, I will compare and contrast fellow two of the most popular forms of studying—periodic and cramming—in an effort to allow high school students to effectively choose which form may best work for them....   [tags: habits, effect, work, study]

Primo Levi’s The Periodic Table Essay

- Primo Levi’s The Periodic Table 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. Primo Levi’s methodology cannot be called purely objective. Being purely objective would mean being not influenced by personal beliefs or feelings....   [tags: Chemisty Chemistry Science Essays]
