mendeleev's name for a column of elements was groups.
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Chlorine and Bromine have similar properties. You can tell because they are in the same vertical column in the periodic table.
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
Alkali metals are in the first column (group) of the Mendeleev periodic table of elements.
"Family of elements" is the synonym of group (column) in the periodic table of Mendeleev.

He "Dmitri" propose that the periodic table of elements that the elements should be grouped by rows and column and by atomic mass,
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Elements arranged in one column exhibit similar chemical properties. Elements in same column also have similar physical properties. Also elements in same column has similar electronic configuration.
Because the table is designed so that elements in the same column tend to have similar properties. The gaps at the top of the table are there to make the elements in vertical columns all have the same amount of outer-shell electrons.
Chlorine and Bromine have similar properties. You can tell because they are in the same vertical column in the periodic table.
