The rows on the Periodic Table correspond to the highest energy level being filled by the elements in that row (period). For example, in period 3, the elements are filling their valence shell in the 3rd energy level from left to right across the period, from 3s1 in sodium to 3s23p6 in argon.
The columns are groups or families, and the rows are periods.
A row on the periodic table is known as a "period" and a column is known as a "group."
The rows in the periodic table are called periods. There are 7 periods in periodic table.

Periodic table comprises of elements arranged in rows and columns.So that the elements having similar properties appear together.
I don't know if you do please write it
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
The columns are called groups (or, sometimes, families). The rows are called periods.
Groups are columns and periods are rows in the periodic table of Mendeleev.
