Vertical columns in periodic table are known as
groups.Horizontal rows are known as periods.There are 18 groups and 7 periods.Maximum principal quantum no. of an element gives us the period no.We can also find the group as follows.
ns1-alkali metals
ns2-alkaline earth metals
ns2 np1-boron family
ns2 np2-carbon family
ns2 np3-pnictogens
ns2 np4-chalcogens
ns2 np5-halogens
