The energy level tells the period in which the element belongs. Also electrons are arranged in different energy levels.
Each period in the periodic table corresponds to a principal energy level.http://wiki.answers.com/Each_period_in_the_periodic_table_corresponds_to_what#ixzz18t3CP9fk
Group 18 or the noble gases.
Notice on the periodic table that 4s comes before the 3d. That is the first place where energy overlap.
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
Each period corresponds to the number of shells (energy levels) contained in the atom.
the energy level increases as we move from top to bottom in the periodic table
Yes, a period is a horizontal row on the periodic table.
There are 3 energy levels in Silicon. Which ever row it is in the Periodic Table, that is how many energy levels it has. The structure is 1s2 2s22p63s23p2
Fah Q
The same number of energy levels
On a periodic table, Sodium onwards (Na)

The higher you are on the periodic table, the less energy levels of electrons there are in each atom, and therefore the less nuclear shielding.
A Period
because of energy levels
the noble gases, in row 18
the principal energy levels of valence electrons increase.
