rows are called periods columns are known as groups
The elements are listed in the order of how many atoms they have. For example, hydrogen is the first element on the periodic table. Hydrogen is the smallest element, and has one atom.
Another name for the columns in the periodic table is "groups." These groups are numbered from 1 to 18, and each group shares similar chemical properties due to the arrangement of electrons in their outer energy levels.
groups are the vertical columns on the periodic table
There are 18 groups in the periodic table of elements.

There is no group named 'you' in the periodic table.the groups in the periodic table are numbered, and have names that identify the general class of elements in that group, e.g. 'halogens'.See this question/answer for more details: What_are_the_group_names_in_the_periodic_table
groups are the vertical columns on the periodic table
There are 18 groups on the periodic table. These groups are columns that contain elements with similar properties due to their shared electron configurations. The groups are numbered 1 to 18, with the first two groups referred to as the "s-block" elements and the last six groups classified as the "p-block" elements.
