Guida verificata passo dopo passo1
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.
