Families Stick Together

The columns of the periodic table are often used to define families. The noble gases are all located in the far right column of the table. That column is labeled Group Zero. Other families can be made of elements in a series. A good example of a series of elements is the transition metal family.
The thing to remember is that a family of elements can be found in several ways. You need to run tests and study the elements to determine their properties. Only after that testing can you determine what family an element belongs in.
