the vertical columns are known as groups
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
Elements with the same number of valence electrons are in the same group (or vertical column).
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
The periodic table is organized in rows and colums called periods and groups. each period in the table helps correspond to the filling of a configuration of the outermost electron shells of their atoms.

no fixed limit
Vertical columns are referred as groups. They are also called families.
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.
It arranges all known elements in a chart of rows and colums of increasing atomic number.
colums are called "families" or "groups". They are all placed in order according to the atomic number, and valend electrons
Elements with the same number of valence electrons are in the same group (or vertical column).
Al, because as you go across the periodic table, atoms get bigger. As you go down colums, they get bigger too. Look up "atomic radii table" if you would like to see it in pictures.

A group in Periodic Table is the column of element in periodic table
It is called the Periodic Table of Elements.
