Location of an element in a periodic table can be given by the period number and the group number. The horizontal row in a periodic table where the elements are present is known as Period. The vertical column in a periodic table where the elements are present is known as Group.
Chemical properties of the elements repeat themselves at regular intervals because of the electronic configuration. The elements that are present in a Group have similar chemical properties. This is because the outer-shell electronic configuration will be the same.
The periodic table has all the elements that can be distinguished based on the outer-shell electron. If the outer-shell electron is present in s subshell, then the elements are present in s area of periodic table. If the outer-shell electron is present in p subshell, then the elements are present in p area of periodic table. If the outer-shell electron is present in d subshell, then the elements are present in d area of periodic table. If the outer-shell electron is present in f subshell, then the elements are present in f area of periodic table.
