In the Periodic Table, a period would be a horizontal row, so named because it was noticed that as the atomic number increased, the elements would periodically evidence similar chemical properties and could thus could be grouped in a way that manifest these similarities. This quality is explained by how electrons fill their orbitals as you progress across the period; elements in the columns having some chemical similarites to others in their column.
