In the periodic table, the family of the element is a vertical column called groups, and the horizontal row containing the element is called a period.
Periods and groups are the part of the periodic table that contains the elements placed in them based on the atomic number, chemical, and physical properties.
The vertical columns are the families or the groups and have similar chemical characteristics and valence electrons. On the other hand, the horizontal row is a period that is seven in number and is based on the shells.
