The period number represents the highest principal quantum number of the valence electrons, or the energy level of the valence (outer) shell.
So, a period represents atoms with the same core electron, or noble gas, configuration, and having the same number of occupied electron shells.
The period number represents the number of shells in a particular element. There are 7 periods in Periodic Table.
gives information about the number of electronic shells
Periods on the periodic table refer to the rows on the periodic table.
what do groups represent
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
Sulfur (S, element number 16) is on the third period of the periodic table.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
a family is a column of elements a period is a row of elements
A period on the periodic table is a row.This is the horizontal section of the periodic table.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.

Period number describes the total number of shells. There are 7 periods in periodic table.
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
The period to which the element belongs
Sulfur (S, element number 16) is on the third period of the periodic table.
Sodium, Na, is in group 1 period 3 on the periodic table.
No. they dont represent the periodic table.
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
The period number of an element is the row in which it appears.
