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 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 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 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.
What is the number of valence electrons for He?
Two valence electrons.
Number of valence electrons in Ga?
3 electrons !
Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
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.
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.
How do you use te periodic table to identify the number of electrons available for bonding?
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
What is the predicted number of valence electrons in barium?
2 is the standard number of valence electrons
How can you find group no?
The number of valence electrons tell us the group number of that element.
