Best Answer

The period number helps in determining the number of shells in the element. For example, Sodium (Na) is in 3rd period that means there are 3 shells in the atom of an Sodium.

What determines an elements location on the periodic table of the elements?

The periodic table is arranged according to the atomic structure of the elements. The atomic structure, specifically the electron arrangement determines the properties of the elements. Elements with the same outer electron configurations have similar properties and are located in the same group.


How does atomic structure link to the periodic table?

The number of protons in the nucleus is equal to an elements atomic number, which determines that element's position in the periodic table.


What does the periodic table describe about an element?

Periodic table describes the symbol, atomic number, mass number of different elements in general.


How is the periodic table used to describe atomic structure?

The periodic table can be used to describe atomic structure by using the period to tell you how many shells (principle quantum number) there are in an element, and the group number can be used to tell you the number of valence electrons in the outermost shell.


Are elements organized by atomic number or atomic mass?

On very early versions of the Periodic Table the elements were organized by atomic mass, because it was measurable and the concept of atomic number was unknown. After Rutherford and Bohr developed their model of the structure of the atom, the Periodic Table was reorganized by atomic number (which caused a few elements to swap positions).


How did chemists organize the elements that were known?

Chemical elements are organized in the periodic table of Mendeleev.
