Periods are the seven horizontal rows on the periodic table. Each period corresponds to a new electron shell being filled with electrons as you move from left to right across the table. The elements in a period start with a metal on the left, transition to metalloids in the middle, and en...

Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. Moving down the table, periods are longer because it takes more electrons to fill the larger and more complex outer levels. Related: Periodic table of elements ...
The periodic table is one of the most commonly used tools of the chemist. Knowing how it is organized is an essential part in being able to use it. Elements are listed in order of increasing atomic number and organized into columns called groups or families. Elements in the same group shar...
