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 on the Periodic Table represents the energy level of the elements' outermost electrons. As you move from left to right across a period, the number of electrons in the outer shell increases, reflecting the trend of increasing atomic number.

A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
What does Periods on the periodic table represent elements?
"Na" is Sodium.
What period on the periodic table does sulfur belong?
Sulfur (S, element number 16) is on the third period of the periodic table.
What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
In the periodic table what is a period?
A period in the periodic table is a row of elements that share the same number of electron shells. Elements within the same period have the same highest energy level.
A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
What does the period number on a periodic table represent?
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.
A period is a horizontal on the periodic table true or false?
False. A period is a horizontal row on the periodic table that corresponds to the number of electron shells in an element's atoms.
What does a period represent on the period 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.
What information on the periodic table does the period number help you with?
Period number describes the total number of shells. There are 7 periods in periodic table.
What does Periods on the periodic table represent elements?
"Na" is Sodium.
What does the numbers on the side of the periodic table represent?
The period to which the element belongs
What period on the periodic table does sulfur belong?
Sulfur (S, element number 16) is on the third period of the periodic table.
What do you call elements in a row on the periodic table?
Elements in a row on the periodic table are called periods. They represent the number of electron shells an element's atoms have. Each period corresponds to the energy level of the electrons in an element's atoms.
What are rows called in Periodic rable?
Rows in the periodic table are called periods. There are seven periods in the periodic table which represent the energy levels of the elements. Each period signifies the number of electron shells an element has.
What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
In the periodic table what is a period?
A period in the periodic table is a row of elements that share the same number of electron shells. Elements within the same period have the same highest energy level.
