It tells you the number of cations in the outer energy level of the element's Atomic Mass
What else can I help you with?
What information do the periods number give you?
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.
What is magnesiums period number?
Magnesium's period number is 3. It is found in period 3 of the periodic table.
What is plutonium period number?
Plutonium is located in period 7 on the periodic table.
The atomic number of sodium the first element in Period 3 is 11 The atomic number of the second element in this period is?

What period number is chlorine?
Chlorine belongs to period 3 on the periodic table.
What does the period number tell about an element?
its tell you the atomics mass that occurs
What does the period number tell us about the element?
For elements it's the atomic number not the "Period Number." This number tells you how many protons a single atom of that element has in its nucleus. The "period number" is a dimensionless quantity used in fluid dynamics.
What does the period number tell about the energy levels occupies by electrons in an atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy level occupied by electrons in an atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy levels occupied by electrons in the atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy levels occupied by electrons in an atom atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
What does the periodic number tell you about the element in the period?
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons
How can you tell which elements of the periodic table are in the same period?
By number of elctrons,protons in them and their reaction rate
What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
Can a guy tell if you are on a period?
No a guy just want be able to tell if you are on a period. Yes, some are able to tell by your behavior.
