First of all birather tune bhoot spelling mistakes kiyai hai .....jaisai "mendelev" = MENDELEEV, and "possed"=posed. Bhai spelling mistake mt kriyo wrna yaha pe AAROHI jasai pgl girls bokhne lgtai gai..

Now come on the point.
The physical and the chemical properties used by mendeleev for creating his periodic table were :-
1.ATOMIC MAAS.....physical property.
2.Similarity in formula of HYDRIDES and OXIDES of various elements.........chemical property.

waisai challenges to bhoot si aai......bt the main two major challenges jo unkai law ko unfollow kr diya wo the :-

1. Anomalous position of some pairs of elements........let explain this.:-

In his periodic table COBALT with higher atomic masses has been placed before NICKEL with low atomic mass. but according to the mendeleev's periodic law.............nickel should be placed before cobalt. Thats it......!!!!

2. POSITION OF ISOTOPES...........i will not explain this becz it kills my to much time.........so plzz help ur self for this.


NOW I HOPE SAMJH ME TOH AA HI GYA HOGA......!!!!!!

Read the passage and answer the questions :Mendeleev was a Russian chemist, who contributed the most for the development of periodic table of elements wherein the elements were arranged on the basis of their fundamental property, the atomic mass and also on the similarity of chemical properties. Only 63 elements were known at his time. He arranged the 63 elements in the increasing order of their atomic masses and found that there was a periodic recurrence of elements with similar physical and chemical properties. He observed that elements with similar properties fall in the same vertical column. These vertical columns are called groups and horizontal rows of elements are called periods. Mendeleev predicted the existence of certain elements not known at that time and named two of them as Eka-silicon and Eka-aluminium.Q. The elements eka aluminium and eka silicon discovered by Mendeleev later found place in the periodic table. Both of these elements belong to
