The long form of the periodic table is the easiest way to study properties of elements. This table is based on the increasing order of atomic number of elements. The elements on the left side of the table are metallic in nature but the right side of the table contains non-metals. We can easily differentiate elements on the basis of metallic and non-metallic nature of the elements. But this classification is not enough for the complete study of elements.
The entire periodic table is divided into 18 vertical columns that are known as groups and 7 horizontal rows, known as periods. The groups of the periodic table are better known with the characteristics of elements. For example; the 1st group of the table is known as alkali metals as these elements form alkalis with water. The second group is known as alkaline earth metals whereas from 3rd to 12th group, elements are commonly known as the transition elements.
Similarly, 13th group is Boron family, the 14th is carbon family, 15th is nitrogen family, 16th is oxygen family and 17th is commonly known as halogen family. These groups are known for their 1st element of the group. Halogen term comes from seawater, as these elements are commonly found in sea water like sodium chloride. Let’s discuss few more properties of halogens.
