Scientists use patterns in the periodic table to what?

I found this on google

“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”

I hope this helps

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))
