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.
22.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
the element sodium has 1,000,000 million energy levels.
One electron in outermost energy level.
it is in the second period. so boron has 2 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.
only 1
The period tells you how many energy levels an atom has.
The period that the element's in is the same number of how many valence electrons (energy level of outer electrons) there are in the element...
2
Electrons in the plutonium atom are placed in 7 energy levels.
see what period it is in on the periodic table it is in period 6, so therefore there are 6 electron shells or energy levels
There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
Aluminium Al: 13 2.8.3 So three energy levels
Bromine has FOUR energy Levels.
