Why do chemists consider periodic table as so useful?

Answer 1

It is useful so they can create more scientific elements

Chemists consider the Periodic Table useful is because it gives information to the atomic number, the average Atomic Mass, The chemical symbol, a general knowledge to valence electrons, basic knowledge that can be used to determine ions, the ability to determine metals, halogens, noble gases, alkalines, nonmetals, etc and this is all just at arm reach.

Answer 2

They don't use them not so many times any more because they know the 'principle' and (more important) they know what they can do with it, without the black magic of semi-chemists.

Short: the use is exaggerated by a lot of people, even teachers. It is a nice table for looking up some facts, but more is in other (simpler) tables.

Answer 3

Chemists and students use the periotic table as a reference tool.

Answer 4

Scientists created periodic table to make study of elements easier. it helps in easy classification.
