groups or families are vertical
A period is a horizontal row in the Periodic Table. Although groups are the most common way of classifying elements, there are some regions of the periodic table where the horizontal trends and similarities in properties are more significant than vertical group trends.
The columns are called groups (or, sometimes, families). The rows are called periods.
The columns in the periodic table are called groups or families. These columns contain elements with similar chemical properties due to their shared number of valence electrons.
Colunms are named 'Groups'. Rows are named 'Periods'.
The columns on a periodic table are called "groups" or "families." These columns contain elements with similar chemical properties due to their shared number of electrons in the outermost energy level.
No. The horizontal rows of the periodic table are called periods. The vertical columns are called groups, and sometimes called families.

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.
