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.

What does the periodic table allow chemists to do?
Periodic table help to estimate the chemical and physical properties of elements.
How chemists use the periodic table?

What type of scientists made the periodic table?
The periodic table was created by chemists, specifically Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights to create a system that displayed the periodic trends of elements.
The first element on the periodic table is what?
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
What are the rows on the a periodic table called?
