What is the definition of a family on the periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
How are families classified in the periodic table?
In the periodic table of elements, there are seven horizontal rows of elements. Each of these rows are called periods. The vertical columns of elements are called groups, or families.
Which is not a family of the periodic table?
Inert gases can be found on the far right of the periodic table with halogens just to the left. Metals make up the center and left side of the table, while fire extinguishers are not any family of elements.

How many families are there in the periodic table of elements?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.
What are the main families of elements?
Families of the Periodic Table. On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.

What makes a family of elements?
The atoms of all elements in most families have the same number of valence electrons. Thus, members of a family in the periodic table share some properties.
