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.
The modern periodic table is a chart containing the elements arranged in order of increasing atomic number. A vertical column, called a group, contains elements with similar properties. A horizontal row is called a period. The atomic number of the elements in a period increases from left to right along the row. Before the development of the modern periodic table, there were other attempts to arrange the elements in a useful way. For example, DÃ¶bereiner arranged groups of three elements with similar properties into âtriads'. Newlands and Mendeleev arranged the elements in order of increasing relative atomic mass.
