THE PERIODIC TABLE OF THE ELEMENTS
Basic elements are usually represented using letters, like
F and H. The rows in the table are called periods, and the
columns are called families or groups. Since there are so
many elements in both the Ln and An families, they’ve
been given their own space at the bottom. Understanding
the structure of the periodic table can really help when
trying to learn about the amazing world of the elements.
