The answer is 18 inner electrons for Calcium (atom number 20)
The first three shells of Ca are 'inner', the last, 4th, contains the 2 valence electrons
So (K,L,M,N) = 2, 8, 8, 2

How many outer shell electrons does calcium have?
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Is the inner lithium shell full?
Yes, Lithium has the Atomic Number 3, therefore has 3 electrons. The inner 'shell' of electrons only needs 2 electrons to be full. The Li+ ion also has a full inner shell.
How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
How can you prevent recurring calcium build-up on your inner eye lid?
In order to prevent recurring calcium build up on your inner eyelid it is important to see an ophthalmologist. Chelation agents can be prescribed by eye doctors to patients with this condition. They are applied to the eyes to remove calcium from the tissues and stop it from forming.
What is the electronic structure of a chlorine atom is 2 8 7?
Yes. 2 electrons in inner shell 8 electrons in next shell 7 electrons in outer shell. (making it a hologen)
What is the shielding constant for calcium (Ca) (Z= Atomic number; Ve= Valence electrons. s =shielding constant or inner electrons?
The shield is the inner electronic
How many electrons does He and Ca have in its outer shell?
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
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 many outer shell electrons does calcium have?
The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons
Is the inner lithium shell full?
Yes, Lithium has the Atomic Number 3, therefore has 3 electrons. The inner 'shell' of electrons only needs 2 electrons to be full. The Li+ ion also has a full inner shell.
Each inner energy level of an atom has a maximum number of?
electrons
What is the maxium number of electrons an element can have on the first inner level?
2
Inner-shell electrons are electrons that?
inner shell electrons : the electrons that are not in the the highest occupied energy level .
What is the factor that affects the atomic number in an element?
More shielding of the outer electrons by the inner electrons is the most important factor that affects the atomic number in an element. A valence electron in an atom is attracted to the nucleus of an atom and is repelled by the other electrons in the atom. The inner electrons shield the outer electrons from the attraction of the nucleus and cause the atomic radius to be larger.
Electrons that are not in the highest occupied energy level are called?
inner-shell electrons
How many electrons are there in the inner shell of hydrogen?
there are 2 electrons in the inner shell of a hydrogen atom.
