Periodic Table
As we know that there are 118 elements present in our Earth.
Around the year 1800, only 30 elements were known. It was quite easy to study and remember the properties of the elements individually.
With the passage of time, the number gradually increased and then became very large. At present as many as 118 elements are known out of which The Identity of 114 elements has been established. The process of discovering new elements is not yet over.
Under the circumstances, it has become rather impossible to study and remember the properties of each element. Scientists felt the necessity of to group elements of similar characteristics together so that if the properties of one of them are known, those of the others could be co-related. This is known as the periodic classification of the elements which is very useful now for Chemistry students, teachers and so on. The real credit for preparing the periodic table goes to Mendeleev. It may be defined as the arrangement of the known elements in certain breaks in such a way so that the elements with similar properties are grouped together.
