All CBSE Notes for Class 11 Chemistry Maths Notes Physics Notes Biology Notes. Enjoy. You don't have to study all the chapters. Here are the complete notes for classification of elements and periodicity in properties class 11 given below. In the periodic table, the elements are arranged in the order of their increasing atomic number.All these elements present several different trends and we can make use of the table formation and the periodic law to understand and predict the chemical, physical, and atomic properties of the elements. 63 elements were known and noble gas were not discovered. Chemistry - Periodic Properties Notes. Properties of elements are the periodic function to their atomic numbers. Periodic Properties . In 1871 he arranged the elements in vertical columns by their atomic mass and found he could get horizontal groups of 3 or 4 that had similar properties. The periodicity in properties is due to repetition of similar outer shell electronic configuration at a certain regular intervals. He determined groups of three elements that had similar properties. Long Form of the Periodic Table or Modern Periodic Table ; The modern periodic table is based on modern periodic law given by Moseley in 1942. Free CBSE revision notes for class 11 Chemistry chapter 3 classification of elements and periodicity in properties can be downloaded here. The periodic table can be printed on a single sheet of paper, but what it contains and can teach us is enormous and beyond measure. Thus, we can say that elements having similar electronic configuration have similar properties. Lanthanides - The 14 elements from 58Ce–71Lu in which 4f-subshell is being progressively filled up are called lanthanides or rare earth elements. Periodic Properties_1 Periodic Properties_2.
