A group or family is a vertical column in the periodic table.
A period is a horizontal row in the Periodic Table. Some groups have specific names also;
alkali metals, alkaline earth metals, halogens, pnictogens, chalcogens, and noble gases. However, some other groups, such as group 7, have no trivial names and are referred to simply by their group numbers, since they display fewer similarities and/or vertical trends.

Columns in a Periodic Table are called groups.They represent elements with similar characteristic. All the elements in a group has same number of valence electron.
The columns are called groups (or, sometimes, families). The rows are called periods.
The elements in the A columns of the periodic table are called representative elements or main group elements. They are grouped into families based on similar chemical properties and valence electron configurations.
Horizontal rows in Periodic Table are called Periods
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
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.
There are 18 groups in the Periodic Table of elements.
They follow a pattern for valence electrons.
The periodic table of elements is the table that arranges different elements based on their common properties in rows and columns. It helps to organize and classify elements by their atomic number, electron configuration, and chemical properties.
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.
There are 18 groups in the periodic table of elements.
