In chemistry, a group (or family) is a vertical column of elements in the periodic table. From left to right, there are a total of 18 groups in the periodic table. Here are the main groups: metals (which includes alkali metals, alkaline earth metals, lanthanides, actinides, transition metals, and post-transition metals), metalloids, and nonmetals (which include reactive nonmetals and noble gases).
Out of 18 numbered groups, the f-block elements between groups 2 and 3 (lanthanides and actinides) do not have any group number.
