Periodic Table Slides chapter 3

Multiple Choice

Why is the periodic table considered a universal blueprint in chemistry?

• Because it organizes elements in a way that reveals patterns and relationships useful for predicting chemical behaviors.

• Because it lists all the elements in alphabetical order.

• Because it is only used by chemists in laboratories.

• Because it was the first table ever created in science.
