There are 18 groups in the periodic table of elements.
There are 18 A columns on the periodic table, also known as the groups. These columns represent elements with similar chemical properties and are numbered from 1 to 18.
For example the elements from the group 1 of the periodic table.

They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
