The Periodic Table the recent version

The periodic Table

The periodic table is a very useful resource in the world of chemistry, it was the result of many years of work by numeros chemist and scientist to find a perfect arrangement for all the known elements. To find the ideal periodic table was a very difficult task as elements present different names and different structures. Until Dmitri Medvedev made the first periodic table, no one before was able to gather all the chemistry elements in a very unique method, he was able to make this table that arrange elements according to the atomic number, electron configurations and chemical proprieties and the result was a very easy to use periodic table that helped chemists before and still doing a lot for chemistry today.
in this post we will present a very unique version of the periodic table so here it is

periodic table of elements





Blocks
When you look and analyse the structure of the periodic table, you will see that each periodic tabel has 5 regions called blocks, they are : S, F, D, P and the G block, this special configuration of the periodic table is due to the Atomic orbitals of each block elements.

Categories
elements of the periodic tables can also be arranged in 3 categories: Metals, Metalloids and Nonmetals. Metals are elements with a very good electric and thermal conductivity and are found in a solid state in the nature also they have a greater density and excellent physical proprieties; Nonmetals regroup gases and solid materials like Chlorine and phosphor compared to the metals, metals have a superior physical and chemical proprieties; metalloids, they come in between they have some of the characteristics of the metals and some of the characteristics of the nonmetals, we can find in the metalloids family elements like Aluminium and Silicone.

Groups or Families
A family in the periodic table is a group of elements that have the same chemical and physical proprieties. Arranged in columns, there are 18 groups or families starting by Alkali metal( the first group) to the last family the Noble gases(trivial name).

Periods
Well in some way a period is very similar to the « group » principal, elements of the same periods have the same proprieties but they don’t belong to the same family or chemical group, also notice that the number of protons and electrons plays a major role in the arrangements of the rows, each time you move from the left to the right in the periodic table you will see that each element has one electron and proton more than the precedent element.

You can find to on the net other versions of the periodic table, the most useful is the one of elements abundance like this one
