Old and Modern Perodic Table
PERIODIC TABLE
PERIODIC TABLE

Charles Janet developed the periodic table in 1928.
How the periodic table is organized:
Charles Janet’s periodic table was organized according all elements that had been discovering before 1928 according to the orbital filling. It also structures the electrons in ascending atomic order
Describe the information the periodic table contains:
DISADVANTAGE:
* The periodic table has a rough tarnation from metal to none-metal.
DISADVANTAGE:
* The periodic table has a rough tarnation from metal to none-metal. ADVANTAGES: * Janet’s periodic table was helpful for writing electrons configurations. * The periodic table was easier to read. * It sectioned off none metal and metal ADVANTAGES: * Janet’s periodic table was helpful for writing electrons configurations. * The periodic table was easier to read. * It sectioned off none metal and metal
The periodic table contains all 63 elements that were discovered before 1928 and contains the number in which they are ordered in.

Dmitri Mendeleev
Dmitri Mendeleev

Dmitri developed this periodic table in 1869. How was the periodic table organised? The periodic table is organised by rows of horizontal row of elements in the periodic table. It is also organised by none metal and metal and was arranged in order of atomic mass What does Dmitri’s periodic table contain? Dmitri’s periodic table contained 58 elements and also contained 4 elements that had not been discovered yet and it contained the atomic mass of the elements. DISADVANTAGES: * When Dmitri put the elements in order of atomic mass, he had trouble getting iodine because iodine was similar properties to chlorine and bromine. But iodine had a low atomic mass. So iodine could not be in his rows. This caused Dmitri to break his own rule; he made for the periodic table.
DISADVANTAGES:
* When Dmitri put the elements in order of atomic mass, he had trouble getting

    Dmitri Mendeleev created the periodic table on March 6, 1869 (almost 100 years, to the day, before my birthdayJ) based on the atomic weights of the elements. Many elements were missing then, but he left spaces for them because he thought one day they might be discovered. Now the periodic table is arranged by the element’s atomic number and many other trends from it can provide valuable information to scientists. When information is arranged in a certain order it is called periodicity. Your assignment is to create your own periodic table using periodicity and similar trends as found in the modern periodic table.…

    Elements are the building blocks of which all things are composed. The elements of Earth are made up of atoms. All atoms possess a nucleus of positively charged protons as wells and neutrons which are neutrally charged. Surrounding the nucleus is a low density area containing negatively charged electrons that are equal to the number of protons within the nucleus. The number of protons within an atom determines the element that it composes. Every element within the Periodic table is defined by its atomic number (the number of protons in the atom). Elements with an atomic number between 1 and 92 are naturally occurring elements. Every element with an atomic number higher than 92 (having a nucleus with more than 92 protons) is a synthetic (man-made) element. The larger the atomic number, the heavier the element.…

    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.…
