The rows or periods in the periodic table represent the main electron energy levels of the atom. Within each main energy level are sublevels that represent an orbital shape and orientation (s, p, d, & f) where electrons are found.

Representative Elements on many periodic tables have a second group number labeled A to represent the number of valence electrons found in the elements of that group. For example, elements in group 2 (2A) have 2 valence electrons, while elements in group 15 (5A) have 5 valence electrons, group 17 (7A) have 7 valence electrons and so on.

Main group elements are indicated in the periodic table in the front of the book by column designations containing an “A”. Main group elements are also called representative elements.

This finding led to the establishment of the Periodic Table – a classification of elements that is based on the periodic nature that those atomic properties vary. Two important features in the Periodic Table are: 1. The horizontal rows are called periods, along which elements are arranged from left to right in order of increasing atomic ...

The (loosely defined) transition metals are the 40 chemical elements 21 to 30, 39 to 48, 71 to 80, and 103 to 112. The name transition comes from their position in the periodic table of elements. In each of the four periods in which they occur, these elements represent the successive addition of electrons to the d atomic orbitals of the atoms.
