How will you distinguish if an element is inert by the number of its valence electrons?

if the outermost shell of an element is completely filled that is, if it has 8 or 18 electrons which makes the outermost shell complete. Than we can say that the element has acquired the inert gas configuration.

You will know the number of valence electrons in an element just by looking on its group in the Periodic Table.
Group refers to the 8 columns in a periodic table (transition metals are not included). For example : Na (sodium) has 1 valence electron since it belongs to group 1, while B (boron) has 3 valence electron since it belongs to group 3.

What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
What is the correct number of valence electron in the element sulfur?
six valence electrons
What is the number of the prinicpal energy level in which valence electrons are found?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What do Valence Electrons determine?

What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
Does the valence electrons equal the number of protons?
Rarely. The number of valence electrons of an element depends on it's position on the periodic table. Any given element can have between 1-8 valence electrons. The number of valence electrons increases left to right on the periodic table, while the number of protons, which determine the atomic mass and identity of an element, increase in general. Therefore the number of valence electrons can only equal the number of protons at the 8th element and below (neon).
The number of electrons in atoms determine in element's propertices?
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How are the number of valence electrons related to the group number?
In s and p blocks the number of valence electrons in an element is the same number of the group which that element belongs to. Hope this helps....
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
What is the number of valence electrons (number in the outer most energy level)?
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
How many valence electrons are in the element fluorine and do the same for chlorine and bromine?
The number of valence electrons is seven.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
