![]() ![]() Reason for the same is that:a)the elements with similar size can be grouped togetherb)the elements with different properties can be grouped togetherc)the elements with similar properties can not be grouped togetherd)the elements with similar properties can be grouped togetherCorrect answer is option 'D'. However, cobalt with atomic mass of 58.93 amu was placed before nickel having an atomic mass of 58.69 amu. Here you can find the meaning of In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses. ![]() Can you explain this answer? covers all topics & solutions for ClExam.įind important definitions, questions, meanings, examples, exercises and tests below for In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses. Information about In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses. The Question and answers have been prepared Can you explain this answer? for Clis part of Class 10 preparation. In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses. more in creating his periodic table ? List two observation which possed a challenge to mendelev's periodic law? What physical and chemical properties of elements were used by the mendelev.more roperties but this was proven wrong So my question is that If it is wrong then if we increase atomic mass by increasing number of protons then also centripetal force between protons in nucleus and between electrons in shells changes? HOW explain me? Mendellev theory is that atomic mass is directly proportional to chemical p.Mendeleev arranged the periodic table on the basis of their fundamental property Mendeleev predicted the existence of certain elements not known at that time and named two of them as Eka-silicon and Eka-aluminium.Q. These vertical columns are called groups and horizontal rows of elements are called periods. He observed that elements with similar properties fall in the same vertical column. 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. more 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. Read the passage and answer the questions :Mendeleev was a Russian chemist.However, cobalt with atomic mass of 58.93 amu was placed before nickel having an atomic mass of 58.69 amu.Reason for the same is that In Mendeleev's periodic table,the elements were arranged in the increasing.
