On the periodic classification of the elementsCIICIICII
Mendeléev arranged the elements based on their (elements) fundamental property, the atomic mass, as well as on the similarity of chemical properties. During the Mendeleev’s time, only 63 elements were known. Mendeléev’s Periodic Table consists of vertical columns known as ‘groups’ and horizo...
Periodic Classification of Elements 5 CHAPTER I n Class IX we have learnt that matter around us is present in the form of elements, compounds and mixtures and the elements contain atoms of only one type. Do you know how many elements are known till date? At present, 114 elements are known...
8.1: Periodic Classification of the Elements The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in ...
Genesis of Periodic Classification 1. Dobereiner’s Triads German chemist Johann Wolfgang Dobereiner attempted to classify elements with similar properties into groups of three elements each. These groups were called ‘triads’. Dobereiner suggested that in these triads, the atomic mass of the element...
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t

The generalisation known as the Periodic Law is in itself a justification of this view: the manner in which interrelationship becomes manifest when they are classified in accordance with its canons, being probably the strongest of all the arguments which can be cited as tending to show that the...
