Without knowing the electronic configurations of the atoms of elements Mendeleev still couldarrange the elements nearlyclose to the arrangements in the Modern periodic table. How canyou appreciate this?
Answers
Mendeleev sticked to his periodic arrangement, He was more concerned to place the similar elements in the same group though sometimes it violated his law of increasing atomic mass. He eventually could know the trend of properties of unknown elements that were not available at his time
This way, He was able to predict new elements and he was also able to arrange the elements like in Modern periodic table.
Hence, We can appreciate Dmitri Mendeleev master mind to have thought to arrange elements as per their properties. And More great achievement was that, His periodic table lead us to invention of more elements. Thus, It also worked as main reference for scientists to carry out their research.
Answer:
Explanation:
mendeleef to consideration about chemical properties while arranging the elements show the arrangement of elements is close to arrangement of elements in Modern Periodic table for this he violated his periodic law he left some gaps for elements later those elements are discovered so the efforts of mentally should be thoroughly appreciated.
