A principal energy level - and more usual a set of Energy Shells [multiple levels of Electron Orbitals and/or Energy Levels].
Each period corresponds to the number of shells (energy levels) contained in the atom.
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
The element in the fourth period is an exception to the Aufbau principle is Cr. Each period in the periodic table corresponds to a principal energy level.
Each (horizontal) row is called a '''period''', whereas each (vertical) column is called a group.
