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.

All the rows on the table are read left to right and each row is called a period. Each column on the table is called a group. Each group has the same number of electrons.
