Element properties are recurring in the periodic table. For example, each row has metals towards the beginning and gasses towards the end (with some exceptions, of course). So, the properties of elements are "periodic". See the nice wikipedia article below.

The simple answer to Your question will be found by looking up a reference for the Russian Chemist DIMITRI MENDELEEV. Basically what He did was to create a table of chemical elements in 1869, in which He listed each element according to the "recurring trends of the element"ie, "periodic" activity.

A period is something that repeats itself over and over. One example of a period is your school day classes...first period, second period etc. Another example of a period which repeats regularly you should be familiar with as a girl. I presume from your name that you are a girl. In the Periodic table the properties of the element repeat themselves regularly as the shells of their atoms fill up and then start again with the next shell.
