Chlorine and Bromine have similar properties. You can tell because they are in the same vertical column in the periodic table.
Elements with similar properties are displayed in columns, called groups, on the periodic table. This arrangement allows elements with similar chemical behavior to be grouped together. Elements in the same group have the same number of valence electrons, which is the main factor determining an element's chemical properties.
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.=
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.
A period on the periodic table is a horizontal row of elements that share similar properties. It helps organize the elements by arranging them in order of increasing atomic number and grouping elements with similar chemical properties together.
Elements in the periodic table with similar qualities are grouped together in columns called groups or families. Elements within the same group share similar chemical properties because they have the same number of valence electrons. This allows them to react in similar ways with other elements.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.

periodic table of elements
The properties of chemical elements have a periodic trend.
Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.
...chemical properties.
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
