The outer shell electron (valence electrons) configuration is the same, hence the same properties.
Chemical properties of elements are largely determined by its outer shell electrons
Each vertical column on the periodic table are called groups, they are also known as families because they have similar chemical properties to each other.
Physical and chemical properties change somewhat regularly across a period. Elements that are close to each other in the same period tend to be more similar than elements that are father apart.
The vertical column in a periodic table is called "The Group" and there are 8 groups in the periodic table, I through O or VIII.They are called Groups or sometimes Families. For many the periodic table has 8 groups but when you also include the transition metals, then there are 18 groups which gives you a better understanding when you are working out the electron arrangement within the atom's structure.
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a 'periodic' way, andarrangedthem so that groups of elements with similar properties fell into vertical columns in his table.

families are vertical columns of elements they have similar chemical and physical properties.

The vertical elements are called groups. They have similar chemical properties.

The members of the same group have similar physical and chemical properties.
The vertical columns called "groups" contain a family of elements i.e., all elements present in a group or family (or the vertical column of a periodic table) have similar chemical properties due to the same number of valence electrons.

In chemistry, a group (also known as a family) is a vertical column in the periodic table of the chemical elements. There are 18 groups in the standard periodic table.
Magnesium, strontium , and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.
Groups are vertical and contain chemical elements with similar properties; periods are horizontal.
