The universe is made of matter and energy. Matter can be elements, compounds and mixtures. Elements are the simplest form of matter which cannot be reduced further. Periodic table is a tool which helps us to have a over view of all the 109 existing elements.

Introduction to Modern Periodic Table of Elements:

The universe is made of matter and energy. Matter can be elements, compounds and mixtures. Elements are the simplest form of matter which cannot be reduced further. Periodic table is a tool which helps us to have a over view of all the 109 existing elements.

Basics of Periodic Table of Classification of Elements

The elements in the periodic table are arranged in the ascending order of their atomic number. Atomic number is the number of electrons present in an atom of an element.

Atoms of all the elements try to get 8 electrons in their outer most shell (valence shell) of the atom (Octet rule). In doing so, each atom gain or lose /share electrons with the atoms of   other elements resulting in the formation of compounds.

The atoms of rare gases or noble gases have their outermost shell (valence shell) completely filled. Hence they do not react.

Features of Modern Periodic Table of Elements

  • The periodic table of elements consists of horizontal rows called periods and vertical columns called groups.
  • There are 18 groups and 7 periods in the periodic table.
  • The elements of group 1 have one valence electron; group 2 elements have 2 valence electrons and so on. Zero group elements have 8 electrons in their outermost shell. Thus the elements of each group have similar properties.
  • Thus one can identify the valence electrons of the atom of the element from the group it is placed.
  • Lanthanides and actinides falling under the same group are shown separately below the table.
  • The elements in I period have their electrons placed in one shell or they have only one main shell.  The elements of the II period have two main shells and so on.
  • Elements on the left side of the periodic table are called metals. Elements on the right side of the periodic table are occupied by non metals. The metals and non metals are separated by metalloids. One can tell that the metals take most part of the table by glancing at it.
  • Metallic to non metallic decreases along a period of the periodic table.

Uses of Modern Periodic Table of Elements:

Knowing the atomic number, it is easy to locate and predict the chemical properties of any element in the periodic table.

The position of the element in the periodic table will help us to write its electronic configuration and identify the valence electrons in the atom of the element.

It reveals the similarities, differences and trends in chemical properties of the elements clearly.

One can easily write the molecular formula and predict the compound formed by the given two elements with the help of the periodic table.
