WebWhere is the 4th period? A period 4 element is an element in the fourth period (row) of the periodic table. It begins at potassium and ends at krypton. Period 4 has 18 elements. Period 4 elements have electrons in the first four electron shells. WebIn accordance with the Aufbau principle, the seven period (1 to 7) have 2,8,8,18,18,32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f - block elements, called lanthanoids and actinoids are placed at the bottom of the main body of the periodic table.
