There are 18 A columns on the periodic table, also known as the groups. These columns represent elements with similar chemical properties and are numbered from 1 to 18.
There are 18 groups in the periodic table of elements.
The columns represent groups or families of elements. There are 18 of them.
For example the elements from the group 1 of the periodic table.
In the periodic table of the elements there are 7 periods and 18 groups. The rows are called periods and columns are called groups. You may be getting confused by the lanthanides and actinides. These groups of elements are found in two rows at the bottom and seem to not be a part of the table. However, if you find and extended version of the table you will see that, technically, these two rows belong in Periods 6 and 7.

There are 18 A columns on the periodic table, also known as the groups. These columns represent elements with similar chemical properties and are numbered from 1 to 18.
The horizontal lines are called "periods" and show how many "shells" each atom hasThe horizontal rows in the periodic table are called periods. The vertical columns are called groups.
There are 18 groups in the periodic table of elements.
The periodic table has 7 rows and 32 columns.
The columns represent groups or families of elements. There are 18 of them.

There are NO vertical ROWS, because rows run horizontally, and COLUMNS run vertically. There are 18 vertical columns in the periodic table.
The vertical column in a periodic table is called "The Group" and there are 8 groups in the periodic table, I through O or VIII.They are called Groups or sometimes Families. For many the periodic table has 8 groups but when you also include the transition metals, then there are 18 groups which gives you a better understanding when you are working out the electron arrangement within the atom's structure.
