A period is a horizontal row in the periodic table. Although groups generally have more significant periodic trends, there are regions where horizontal trends are more significant than vertical group trends, such as the f-block, where the lanthanides and actinides form two substantial horizontal series of elements.
Groups and periods are two ways of categorizing elements on the periodic table. Here is how to tell them apart and how they related to periodic table trends. Answer: Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases both as you move down a group or across a period. Elements in a group share a common number of valence electrons.
