The periodic table is grouped because of their chacteristics. They have similarities and differences, of course. Groups are also known as families or groups of the same characteristics.Periods, on the other hand, are the rows of the periodic table, containing atoms of similar atomic number.
At a more fundamental level, the elements are grouped by the number of electrons in the "outer shell", i.e. the highest energy level in which electrons sit within the atom. These energy levels are themselves subdivided into orbitals, as represented by the different "blocks" of the periodic table. For example:Strontium (Sr) has 38 electrons. These are arranged into five main energy levels, or shells (Period 5). The outer of these shells contains two electrons (Group 2) which lie in the S-subshell (S block).
The Periodic Table is arranged in groups based on the number of valence electrons each element has. Elements in the same group tend to have similar chemical properties due to their shared outer electron configuration. Each group has a designated number that corresponds to the number of valence electrons the elements in that group possess.
So it is easier to read and gather information from. It also displays information by being in separate groups, for example you know if an element is a metal or nonmetal depending where it is on the table. Also the different groups and families mean different things, like how many electrons are in each element.
Most of the groups in the periodic table are made to help display the relations of the different elements in the table. Like the elements in the noble gases family are all gases, and why do I know that? Because of the column they are all in. The different groups help you to understand the table's deep meaning.
The elements within a group have the same number of valence electrons in their outermost energy levels, and they have similar properties.
Elements are grouped in such order to easily identify elements and their basic statistics.
Elements are classified into different groups for their systematic study.
So it is easier to find the one or the type/family/group you're looking for. Common Sense. :D hope useful

How many groups of elements in periodic table?
There are 18 groups of elements in the periodic table, each representing a column of elements that share similar properties.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
What are the columns in the periodic are called?
The columns in the periodic table are called groups or families. Each group contains elements with similar chemical properties due to their similar electron configurations.
How many periods and groups are on the modern periodic table?
There are 7 periods and 18 groups on the modern periodic table. Periods refer to horizontal rows while groups refer to vertical columns on the table.
