First shell has 2 electrons. Next shell has 8 electrons. The third shell has 18 but scientist say 8 so they don't confuse graphs.
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.
Noble gases already has full valence 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.
The third shell can hold a maximum of 18 electrons. It has three subshells - 3s, 3p, and 3d - which can accommodate a total of 18 electrons.
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
Third Shell
Sulfur has six electrons in its third electron shell.
The third last shell. What a mouthful!
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
It is sodium Chlorine is the first element that needs a 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.
Sulfur
Sulfa.
11 electrons makes the third energy level complete. One
11 electrons makes the third energy level complete. One
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.
