The period tells you how many energy levels an atom has.
You can determine the number of energy levels an element possesses by looking at its period number on the periodic table. Each period corresponds to a different energy level, so the period number indicates how many energy levels the element has.
The element's period indicates the number of energy levels or electron shells that its electrons occupy. Each period corresponds to a new energy level being filled by electrons. Moving from left to right across a period, the number of energy levels increases by one as you go from one element to the next.
