The period number is equal to the number of energy levels. Elements of period 3 have 3 energy levels. Na,Mg,Al,Si are few elements in the period 3.
Bromine has FOUR energy Levels.
Iodine has seven energy levels.
Chlorine has three electron shells with 2, 8, 7 electrons.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
the element sodium has 1,000,000 million energy levels.
Potassium is in the 4th period and has 4 energy levels.
Elements in the second period have two principal energy level. The first energy level has one s subshell. The second energy level has one s subshell and three p subshells.

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.
2
it is in the second period. so boron has 2 energy levels
Electrons in the plutonium atom are placed in 7 energy levels.
Bromine has FOUR energy Levels.
Arsenic has 8 levels of energy.
Germanium has 4 energy levels.
