Whereas the vertical columns on the Periodic Table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
