False; That would be called groups. Periods are horiztonal rows.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
There seems to be a typo in your question. If you meant a "horizontal row" (left to right) of the periodic table, those are called periods. If you meant a "vertical column" (up and down) of the periodic table, those are called groups.
A vertical column is called a 'group.' A horizontal row is called a 'period,' thus the periodic table.
The horizontal rows in the periodic table are called periods, and the vertical columns are called groups or families. Periods indicate the number of electron shells an element has, while groups determine the number of valence electrons.
A horizontal row on the periodic table of elements is called a period.
The vertical columns in a periodic table are called groups, and the horizontal rows are called periods.
The horizontal rows on the periodic table are called periods, while the vertical columns are called groups or families.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
The horizontal rows are named 'PERIODS'. The vertical columns are named 'GROUPS'.
The Horizontal Rows are named 'PERIODS'. The Vertical Columns are named 'GROUPS'.
Horizontal rows are called groups. Groups are formed according to the atomic number.
Horizontal rows are called groups. Groups are formed according to the atomic number.
Horizontal rows are called Periods, while vertical columns are called Groups.
The vertical rows on the periodic table are called groups.The vertical rows are called periods and the horizontal columns are called groups.

A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
The rows (Horizontal) are called Periods and the Columms (Vertical) are called Groups.
