The Periodic table of elements was created by a Russian scientist named Dmitry Ivanovich Mendeleev. When he created it in 1869 not a lot of elements had been discovered. He put the table together using the elements atomic number. Hydrogen for example is first on the periodic table because it's atomic number is one. When he completed it there were a lot of gaps. What Dmitry did was he actually predicted the existence of other elements where the gaps were on the periodic table. A lot of the elements have been found but a few are still 'unobserved'. The periodic table is set out using it's atomic number. There is also the AMU which is the atomic mass unit but it does not have much to do with the set out of the periodic table.

The table of element is periodic in one way. It is periodic is repeating patterns.


The periodic table of elements is a way to organize the elements based on atomic number and chemical property


The modern periodic table was developed because there was a need to organise elements in a way elements can easily be found (on the table) and for periodic trends to be observed.


The table shows recurring, or periodic, chemical properties in the elements.


The periodic table of elements is an arrangement of the elements on a table that allows us to quickly find out some things about a given element and its chemistry. Use the link below to get the full scoop on why the periodic table is arranged the way it is. It's the Related question, "In the periodic table what are the elements arranged by?"


The periodic table of elements came into existence while Dmitri Mendeleev was writing his textbook, The Principles of Chemistry. He came up with a way of organizing the elements in order of atomic weight.


mendeleev left some gaps in periodic table for elements for future element , in this way he organized periodic table..............:)


The periodic table of the elements organizes chemical knowledge about the various elements in a way that enables us to understand why different elements have the chemical properties that they have.




The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.


The periodic table of elements was invented by the Russian chemist Dmitri Mendeleev and nowadays it's the most common way to tabulate the elements.


No it is the other way around. The majority of elements in the periodic table are metals.


The elements are listed in ascending order, according to their atomic number. The periodic table is arranged in such a way that elements in the same column tend to have similar properties.


The periodic table shows the atomic number, symbol, mass number, density of an element. Elements are arranged in periodic table such that their physical and chemical properties follows varies in a systematic way.


The basic idea is that when arranged in a certain way (the way presented in the periodic table), elements in the same column tend to have similar properties.


Mendeleev found properties of elements to be the periodic function of atomic mass. So, he arranged element that way.


The way the elements are sorted are by block and period. Hence periodic.


None. The periodic table of elements is a convenient way to display all known elements, song with a few fundamental properties of each. No 'laws' are captured here.


The periodic table is set out in a pattern that provides a great deal of information about the elements. Understanding the way the table is structured will help to understand how elements will behave and react. A study of the patterns will be a great aid in learning about chemicals and why they work in the way they do.


The second lightest element on the periodic table is Helium (He). The easiest way to tell this is by the numbers on the periodic table, all elements are in atomic weight order (super-light gases to super-heavy elements).


it is one of the elements in the Periodic Table of the Elements, so yes, aluminum is a pure element. Steel is simply iron tempered in a different way, and thus is not on the Periodic Table.


It can not. The table is just a organized way to write the elements.



Dmitri Ivanovich Mendeleev created a periodic table to sort elements.
