what do you mean by priodic classification of elements

Answer 1

Periodic Classification of Elements – Present form ofperiodic table (Long form) Based on the modern periodiclaw, the elements arearranged into rows and columns based on their atomic number. There are 18 columns, called groups and 7 rows, called periods.

Answer 2

The table can be used to predict properties of elements, even those that have not been discovered. Columns (groups) and rows (periods) indicate elements that share similar characteristics. The table makes trends in element properties apparent. The table provides important information used to balance chemical equations. It is difficult to study each and every element individually and to know its properties and uses. Therefore, they have been classified into groups on the basis of their similarities in properties.
