INORGANIC CHEMISTRY TIE
Introduction
Periodic is the process of arranging elements in a tabular
display called a periodic table. The arrangement of the elements is based
on the similarities and differences in physical and chemical properties. The
primary objective of the classification is to arrange the known facts about the
elements so that they can be learnt easily. An understanding of the concept
of periodic classification simplifies the study of the physical and chemical
properties of the elements as well as their uses. In this chapter, you will
learn about the concept of periodicity, periodic trends in the properties of
the elements, and the diagonal relationships of the elements in the periodic
table.
1.1 Concept of periodicity
Periodicity is a tendency of a particular property of an element to appear
every after a certain specific interval in a given arrangement. In this section,
you will learn about the efforts of different scientists in trying to classify
elements, main features of the modern periodic table, and comparison of the
Periodic Law in terms of atomic masses and atomic numbers.
1.1.1 Development of the modern periodic table
The modern periodic table is a result of efforts of some prominent scientists
who utilised their time to learn how best they could arrange the elements
based on similar physical and chemical properties. The development of the
modern periodic table is therefore associated with several ideas of scientists
