18
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.

there are 7 periods in the periodic table118

In the periodic table of the elements there are 7 periods and 18 groups. The rows are called periods and columns are called groups. You may be getting confused by the lanthanides and actinides. These groups of elements are found in two rows at the bottom and seem to not be a part of the table. However, if you find and extended version of the table you will see that, technically, these two rows belong in Periods 6 and 7.
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
