    Some Important Points and Terms of the Chapter 1. Dobereiner's Triads:In 1817 a German chemist Doberneiner identified certain groups of three elements. These groups of three elements having similar properties was called triads. When three elements were arranged in order of their increasing atomic masses, the atomic mass of the middle element was roughly the mean of the atomic masses of the other two element 2. New Lands Law of octaves:When elements were arranged in order of their increasing relative atomic masses. The properties of every eight elements were similar to the first one, like the eighth note of a musical scale.This repetition in the properties of elements is just like the repetition of eighth node in an octave of music. 3. Mendeleev's Periodic Law:The physical and chemical properties of elements are the periodic function of their atomic masses. 4. Mendeleev's Periodic Table:When mendeleev started his work, 63 elements were known at that time. He selected hydrogen and oxygen as they are very reactive and formed compounds with most elements. Mendeleev's periodic table contains vertical columns called groups and horizontal rows called periods. There were 7 periods and 8 groups. Noble gases were not known at that time. So there was no group of noble gases.The elements in each group of the periodic tables are similar to one another in many properties. The similar properties of the elements are repeated periodically (a).Merits of mendeleev's classification  Mendeleev's periodic law predicted the existence of some elements that had not been discovered at that time  .Could predict the properties of several elements on the basis of their position in the periodic table.  Could accommodate noble gases when they were discovered. (b)Limitations of mendeleev's classification :-  The correct position could not be assigned to the hydrogen in the periodic table.  Wrong order of the atomic masses of some elements could not be explained.
