groups
The horizontal rows are named 'PERIODS'. The vertical columns are named 'GROUPS'.
The rows (Horizontal) are called Periods and the Columms (Vertical) are called Groups.
It is called the Periodic Table of Elements.

The "vertical" column of the periodic table is called the "group" (from group I, with Hydrogen at the top, then Lithium, Sodium, Potasium, Rubidium, Cesium and Francium at the bottom of that group; To group VIII with Helium at the top, working down to ununoctium at the bottom). The horizontal column is called a "period". e.g, period 1, has the element Hydrogen to Helium from left to right of the periodic table, Whereas period 7, has the elements Francium, Radium, Actinium, Rutherfordium, dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, Ununbium, Ununtrium, Ununquadium, Ununpentium, Ununhexium, Ununseptium and Ununoctium, from left to right of the periodic table!
The vertical columns of the periodic table are called groups or families.
The columns on the periodic table are called Groups.
groups are the vertical columns on the periodic table
The vertical columns in a periodic table are called Groups.
The columns are known as groups.
There are 18 columns on the periodic table.They are called groups or families.
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
The columns are called groups (or, sometimes, families). The rows are called periods.
The vertical columns of a periodic table are called groups or families. They share similar chemical properties because they have the same number of valence electrons.
