Is valance shell full i sodium?
No, the valence shell of sodium (Na) is not full. Sodium has an atomic number of 11, which means it has 11 electrons, with 1 electron in its outermost shell (the third shell). This single valence electron makes sodium highly reactive, as it tends to lose that electron to achieve a full outer shell, resembling the electron configuration of the nearest noble gas, neon.
How many places are there for a electrons in the third sheel of an atom?
In the third shell of an atom, there are a total of 18 possible electron positions. This shell can hold up to 2n² electrons, where n is the principal quantum number of the shell. For the third shell (n=3), this calculation gives 2(3)² = 18 electrons. The third shell includes the s, p, and d subshells, which can accommodate these electrons.
How many electrons are in the first shell second shell and third shell of neon?
It depends what electronic state it's found in, but in it's ground state (natural form) it has two electrons in the first shell, eight in the second and none in the third. This is because it has an atomic number of 10. 2+8 = 10.
What group of elements already has a full shell?
Noble gases already has full valence shell
What element has 7 valences in its third shell?
The element that has 7 valence electrons in its third shell is chlorine. The electronic configuration of chlorine is 2, 8, 7, with the outermost shell containing 7 electrons.

How many electrons does sulfur have in its third electron shell?
Sulfur has six electrons in its third electron shell.
What is antepenultimte shell?
The third last shell. What a mouthful!
Does calcium have a full outer shell?
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
What is the first element that need a third shell?
It is sodium Chlorine is the first element that needs a third shell.
What element has 2 electrons in the first shell 8 second shell and 6 in the third shell?
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
How many additional valence shells does chlorine need to have a full valence shell?
11 electrons makes the third energy level complete. One

Sulfur
What has 2 electrons in the first shell 8 in the secod shell and 6 in the third shell?
Sulfa.
How many completely full electron shells do the elements in the third row contain?
Elements in the third row of the periodic table have 3 completely full electron shells. This means they have all 8 electrons in the first shell, all 8 electrons in the second shell, and all 18 electrons in the third shell.
