hey guys welcome to my channel again.

In this video we will discuss about the #mendeleev #periodic #classification of #elements. 
In this video we will discuss about mendeleev periodic law ok about the arrangement of elements in mendeleev periodic table and
 the #merits of mendeleev periodic table and 
what are the #limitations of mendeleev periodic table will discuss about these topics.

#introduction
Dmitri Ivanovich Mendeleev, a Russian scientist arranged the elements in increasing order of their relative atomic masses. He was honored with Noble prize in 1906 for his Periodic Table.

#mendeleevperiodiclaw
Mendeleev’s Periodic Law states that the properties of elements are the periodic function of their relative atomic masses.

 #arrangementofelements
Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev’s Periodic Table. He divided the table in eight columns and seven rows. The columns are known as groups and rows are known as periods.

 Elements are arranged in the periodic table in the increasing order of their relative atomic masses.

Mendeleev divided his periodic table in eight groups and seven periods.

Groups from I to VII are meant for normal elements and group VIII is for transition elements.

Groups from I to VII have been divided in two sub groups, while group VIII is meant for three elements.

Periods from 4th to 7th have been divided in two series: 1st series and 2nd series.

Elements having similar properties have been kept in the same group. For example; lithium, potassium, rubidium, etc. are in 1st group.
