Why Is the Periodic Table Periodic

Unnecessary Title that’s bold, italicized, and underlined.

The periodic table is a chart of elements set up on the bias of atomic numbers, chemical properties, and their electron configurations. The elements of this chart are organized in families/groups and periods. The word periodic refers to the way the table is ordered, which is in periods and families/groups, and it looks like this:
The green ones are the non-metals, the blue ones are alkali metals, the red ones are the alkaline earth, the yellow are the transition metals, the light blue ones are other metals, the purple ones are the metalloids, the pink ones are the halogens, the brown ones are the noble gases, and the gold ones are the rare earth metals. In terms of mass and atomic number, the periodic table reads left to right, and top to bottom. The families/groups are in vertical rows, and all share very similar properties. The noble gas family/group on the right are all similarly un-reactive. The alkali metals on the left are all highly reactive. To summarize everything I just said, I believe the periodic table is periodic because of its overall tear-jerking-ly beautiful structure. It flows like the English words of a book, from left to right, top to bottom. It sorts itself vertically into groups/families that share similar properties. It always keeps similarly classified elements grouped together on the table itself. I consulted with Alex and she also agrees with me in the belief that the periodic table is periodic because of its periodical structure. She agrees that its flow of left to right, top to bottom, and its grouping into families are all reasons that the periodic table is

    The periodic table is composed of eighteen columns and seven horizontal rows, with two additional rows underneath. There is grand total of 112 elements in the periodic table, each of which is placed in a designated spot on the table and cannot be moved. Different areas on the table have elements that are made of different components. Elements that are in the same column are more similar than elements in the same horizontal row. Seventy five percent of the table is made up of metals, and a couple of the columns on the right of the table have gases. There are only two elements that are liquids- mercury and bromine. Column 1 contains the alkali metals, which suddenly combust when exposed to air or water. Columns 3-12 are the transition metals, which contain heavier atoms, which are more flexible in how they organize their electrons. Column 17 is made up of the more reactive gases- the halogens. The noble gases are in column 18. The electrons are the most significant part of an atom. When atoms don’t have the sufficient number of electrons they need in their outer level, they will do whatever they can to get the number they need. The number of protons an atom has is its atomic number. The atomic number plus the number of neutrons the atom has is the atom’s atomic weight.…

    2. The reactivity of the metal increases with each period it goes down. Magnesium is the least reactive and is in the third period with an atomic number of 12. Calcium is slightly more reactive being in the fourth period and having an atomic number of 20. Barium is the most reactive because it is in the sixth period and it has an atomic number of 56. So the farther down in the group they go the more reactive they are.…

    Here are some questions about the elements, their properties, and periodicity. In each case, the correct answer is the name of an element (one of the two given). Write the answer in the appropriate space at the right, placing the first letter in the first blank. There are more than enough blanks to fit either element name, so the number of letters in the name cannot be used as a clue. When the puzzle is complete, the Periodic Law will be displayed in the highlighted column.( by Bronwyn J. Nelson, Fairfield High School, Fairfield, Ohio.)…

    Dmitri Mendeleev’s Periodic table is based on atomic weight, whereas, the modern periodic table keeps the atomic number as the base. An atomic table arranges elements from left to right in a row with the atomic number and properties gradually changing. The elements on the next row will actually exhibit similar properties as the ones above or below it. This provides an example of the periodicity nature of the elements. The columns of different elements in a period have the same or very similar properties. The properties of the elements change gradually as the columns move down through the periodic table. Atoms in similar families, such as H2S and H2O, exhibit both similar properties and molecular structure. This shows periodicity in both the molecules and the individual atoms.…

    1. I just returned home from being interviewed for a new public television program on the mystery of matter and the search for the elements. It was very gratifying to see how keen the film-makers were on understanding precisely how Mendeleev arrived at his famous first periodic table of 1869. This in turn meant that I had to thoroughly review the literature on this particular historical episode, which will form the basis of this blog.…

    Dmitri Ivanovich Mendeleev (1834-1907) was a Russian chemist famous for his formulation of classification of elements, or what is now called the Periodic Table of Elements (2011). On 6 March 1869, Mendeleev made a formal presentation to the Russian Chemical Society, titled “The Dependence between the Properties of the Atomic Weights of the Elements”, which described elements according to both atomic weight and valence. This presentation stated that: the elements, if arranged according to their atomic weight, exhibit an apparent periodicity of properties; elements which are similar in regards to their chemical properties have atomic weights which are either of nearly the same value (e.g., Pt, Ir, Os) or which increase regularly (e.g., K, Rb, Cs); the arrangement of the elements in groups of elements in the order of their atomic weights corresponds to their so-called valence’s, as well as, to some extent, their distinctive chemical properties; as is apparent among other series in that of Li, Be, B, C, N, O, and F; the elements which are the most widely diffused have small atomic weights; and that the magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body (2011).…

    The periodic is a table of the elements, organized in order of increasing atomic number. Elements that have similar chemical properties and electronic structures appear in vertical columns, or also called groups. The Periodic Law states that when elements are placed in order of increasing atomic number, their physical and chemical properties display a periodic pattern. The purpose of the lab was to discover how two periodic properties, atomic radius, and first ionization energy, vary with the atomic number for the first 20 elements.…

    Chemists are able to make many things once they understand the periodic table. For example, if a person wants to clean in his/her bathroom, they would probably use bleach, which is a sodium hypochlorite liquid and calcium hypochlorite as a solid. When a person uses soap to take a bath, they are using an element from the periodic table as well. The elements on the periodic table are widely used all over the world. Out of all the elements on the periodic table, noble gases are the most remarkable, because of their history on how and when they were found, their location on the periodic table, and how they are used in this world today. As time goes on, the elements will continue to be discovered by intelligent people, and the periodic table will continue to…
