The horizontal rows on the periodic table are called periods.

Groups and families on the periodic table. In chemistry a group also known as a family is a column of elements in the periodic table of the chemical elements. Recognizing families on the periodic table columns of the periodic tabletypically mark groups or families. In the periodic table of elements there are seven horizontal rows of elements called periods.

All the members of a family of elements have the same number of valence electrons and similar chemical properties. The f block columns between groups 3 and 4 are not numbered. In the periodic table of the elements each numbered column is a group.

Periods in the periodic table. Three systems have been used to number families and groups. Element families are elements that have the same number of valence electrons.

The periodic table can be divided into nine families of elements each having similar properties. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms i e the same core charge because most chemical properties are. Most element families are a single column of the periodic table although the transition elements consist of several columns plus the elements located below the main body of the table.

The vertical columns of elements are called groups or families. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. The periodic table families this periodic table shows that there is nine different families some example are the non metals and alkali metals and so forth down the line as seen on the image to the side.

An example of an element family is the nitrogen group or pnictogens. The most common way the periodic table is classified by metals nonmetals and metalloids.
