What is the difference between a row and a period?

In the context of the Periodic Table, a row is called a "period," which represents elements with the same number of electron shells. As you move across a period from left to right, the atomic number increases, and elements exhibit varying properties. In a broader context, a "row" generally refers to any horizontal line of items or data, while "period" can refer to a segment in time or a specific interval in various fields. Thus, while all periods are rows, not all rows are periods.
