they are arranged in the increasing order of their atomic number from left to right.
the horizontal rows are known are periods and the vertical columns are known as groups.
elements in the same group have same number of valence electrons and hence have similar properties.
further the elements can be classified based on the orbitals in which the valence electrons enter and can be classified as s-, p-, d- or f-block elements.
the periodic table.
A tool to organize the elements
Demitri Mendeleev discovered a pattern to the periodic table in 1869.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.

It is called the Periodic Table of Elements.
It is The Periodic Table of Elements
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.
There are 53 Elements in the Periodic Table.
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
Elements are arranged in the increasing order of their atomic number in the periodic table.
