What term describes a row on the periodic table?

Explanation:
Rows on the periodic table are called periods. This is a horizontal arrangement, so moving left to right you’re adding electrons to the same principal energy level, meaning the outer-shell level stays the same within a period. In contrast, vertical columns are groups or families, describing sets of elements with similar chemistry. So the term for a row is period.
