Question

what is mean periodic classification of elements? why it is necess?​

Answer 1

Answer: the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in which elements in the same column (group) have similar properties.

It is also necessary to understand how they form the compounds. Grouping of elements into different classes is called periodic classification of elements. This method is requires arranging the elements that are alike and separating the elements that are unlike. To compare the properties of elements.
