if the no of atoms in the last shell is less than four,write the no of atoms down.
if it is more than four,subtract the no from eight.
the no is the valency

How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
How can you determine the number a valence electron an atom has?
you must plot out the element like protonéatomic number by using the bhor diagram
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.
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 is the predicted number of valence electrons in barium?
2 is the standard number of valence electrons
How can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
How do you find the number of non-valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
How do you find valence number of aluminium chloride?
6
How do you find the valence electron?
If you can find a dot diagram, look at the outer shell and count the electrons. The outer electrons is the amount of valence electrons.
How can you find group no?
The number of valence electrons tell us the group number of that element.

How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
How do you get the total number of valence electron?
if we find the electronic configuration, by 2n^2 rule, we can find it
What is a positive valence number?
its a valence number which is and above
How can you determine the number of valence electrons in an atom of a representative?
To find the number of valence electrons in an atom of a representative element, all you have to do is look at its group number. Ex: Group 1 (Hydrogen, Lithium, Sodium, Potassium, ect.) All have 1 valence electron.
How can you determine the number a valence electron an atom has?
you must plot out the element like protonéatomic number by using the bhor diagram
