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 electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence 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 maximum number of electrons in second electron level?
The maximum number is 8 electrons in the second shell.
How many electrons in Sodium Oxide?
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
How many electrons are in mendelevium?
101 electrons...to find the number of electrons in an element, you need to know the number of protons. There are the same amount of protons as electrons. The number of protons is the same number as the atomic number. Mendelevium has 101 as its atomic number therefore 101 protons and therefore 101 electrons.
What energy level are carbon's valence electrons?
Two valence electrons at second s- and p-level each: 2s2 2p2 The other two are nonvalence electrons on 1st s-level: 1s2
What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
The question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?This question may seem hard and/or confusing, but it's really not. You just have to think about it for a minute. This question was in my science quiz online. I had to take LOTS of notes, and guess what?, the answer was right there in my notes..The notes that I took for this question had the topic:Electrons in an ElementMy notes were:-Electrons occupy the electron cloud.-Each electron occupies an energy state.-Electrons farther from the nucleus occupy a higher energy state.-The electron cloud is divided into energy levels.-Each energy level can hold a certain number of electrons-Valence Electrons are usually found in the highest energy level.Not very much notes, but lots of information, and most of them are about energy, and one is about Valence electrons. So, let's figure this.If a valence electron usually have the highest energy level, then a nonvalence electron must not have any energy levels. So, what you would have to add to the nonvalence electron is add energy to become a valence electron.Our question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?So the answer to our question is: Energy. Energy can be added.
How do you find electrons?
you can find electrons by subtract the atomic number and atomic mass.
How can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
Find the number of electrons in boron?
there are 5 electrons in boron
How do you find the mass number without knowing the number of electrons?
The mass number doesn't depends on the number of electrons.
How do you find electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
How can you find he number of electrons in an atom?
in an atom of neutral charge, the number of electrons will be the same as the number of protons, or the atomic number.
How can you find the number of electrons an element has?
In a neutral atom the number of electrons is the same as the atomic number, which is the number of protons in the nucleus.
How do you find the electrons?
electron=atomic number
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
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)
