The periodic table of elements is the table that arranges different elements based on their common properties in rows and columns. It helps to organize and classify elements by their atomic number, electron configuration, and chemical properties.
Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.
each row in the Periodic Table is called a period.
