What Is A Group Or Family On The Periodic Table

A group or family is the vertical columns on the periodic table of the elements.

The columns of the periodic table are often used to define families. Both describe elements that share common properties usually based on the number of valence electrons. In chemistry a family is a group of elements with similar chemical properties. Periodic table in chemistry the organized array of all the chemical elements in order of increasing atomic number.

The group family with elements cotaining full outer shells are the right most group on the table. There are 18 numbered groups in the periodic table. The horizontal rows on the periodic table are called periods. In chemistry a group also known as a family is a column of elements in the periodic table of the chemical elements.

When the elements are thus arranged there is a recurring pattern called the periodic law in their properties in which elements in the same column group have similar properties. A good example of a series of elements is the transition metal family. The f block columns between groups 3 and 4 are not numbered. The alkali and alkaline earth and transitions are all groups of the periodic table another point of view.

The noble gases are all located in the far right column of the table. Other families can be made of elements in a series. Helium neon argon krypton xenon and radon element 118 oganesson also belongs in this group but most all of its chemical and physical properties are as of yet unknown. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

Chemical families tend to be associated with the vertical columns on the periodic table. We re not even sure if it s a gas these elements are all generally inert and unreactive and do not. That column is labeled group zero. Usually either family or group refers to one or more columns of the periodic table.

However some texts chemists and teachers distinguish between the two sets of elements. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. The most common way the periodic table is classified by metals nonmetals and metalloids.
