What is the main advantage of the periodic table
Everything is made of some smaller form of chemical element combinations, even from the stars. Elements are seperately listed size-wise in a "Periodic Table", which also indicates other details about each element.
All the elements are there you have a visual and there's numbers on it I just can't remember what they stand for at the moment
I think it's mostly used for learning about the atomic # the numbers let you know what can be combined together
The periodic table describes in a systematic way all of the known elements that stand between us and the abyss.
If you are talking about modern periodic table then you can easily search elements of same valency in same group and all the elements are arranged in their atomic no.
