What is the necessity of arranging element in the periodic table ?
Answers
Before all the naturally-occurring elements were discovered, the periodic table was used to predict the chemical and physical properties of elements in the gaps on the table.
Today, the table can be used to predict properties of elements yet to be discovered, although these new elements are all highly radioactive and break down into more familiar elements almost instantly. The table is useful for modern students and scientists because it helps predict the types of chemical reactions that are likely for an element. Rather than memorize facts and figures for each element, a quick glance at the table reveals a lot about the reactivity of an element, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics.
