Understand that the modern periodic table is organized into vertical columns called groups, which classify elements with similar chemical properties.
Recall that the groups are numbered from 1 to 18, representing the main columns in the periodic table.
Recognize that these 18 groups include both the s-block, p-block, and d-block elements, covering all main families of elements.
Note that the number 7 corresponds to periods (horizontal rows), not groups, and 36 or 8 do not match the standard group count.
Conclude that the modern periodic table contains 18 groups, which is the total number of vertical columns.
