$\Huge{\mathfrak{\blue{\underline{ANSWER}}}}$

➖Before 18th century, only a few elements are known & it was quite east to study their chemical & physical properties.

➖But with the passage of time, more & more elements were discovered & it was not possible to study & remember each of them individually .

➖Because many of them have different properties.

➖So, there arise the need of developing a table or chart in which all the elements can be classified according to similar properties ,so that less confusion can be generated & true information can be generated about the different elements present in periodic table.
