Unit #4 THE PERIODIC TABLE

4.2 - The Groups

There are 18 vertical columns of elements in the periodic table. Each column is called a group of elements, or a family of elements. Elements in the same family or group tend to have similar properties.

There are two formats in labelling the groups on the periodic table. In some books (and on the Internet) you will find the "1-18" numbering sequence. In other books, you will find the more popular "1-8 A and B" group labelling system. In this course, we will use the latter system of labelling.


Learn the names and read about the elements belonging to Group IA, Group IIA, Group VIIA and Group VIIIA.

"A" elements
The
Representative
Elements
Group IA Alkali metals (4.2.1)
Group IIA Alkaline earth metals (4.2.2)
Group VIIA Halogens (4.2.3)
Group VIIIA Noble gases (4.2.4)*
"B" elements
  1. The Transition Elements
  2. Inner Transition Metals
(details of the transition elements are not covered in this course)

Click here to check out the elements of the periodic table listed by groups. Click on the above links and read up on the alkali metals, alkaline earth elements, halogens and noble gases.

(* This group is sometimes referred to as the Inert gases.)
