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.

What group of elements already has a full shell?
Noble gases already has full valence shell
Each atom is left with a what outer shell?
Electron outer shell tee hee =^-^=
Is the outer shell of nickel full?
no its outside shell has 10/18 electrons
How many electrons are found on the third shell of helium?
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
If the outer shell of the atom is full it react readily with other atoms?
If the outer shell of the atom is full, it ________ react readily with other atoms.Answer - Does not!
An atom of chlorine has several valence electrons in its what A nucleus Bfirst shell C second shell D third shell?
Third Shell
Is nickel electron shell full or not full?
nickel's outside electron shell is not full.
What is antepenultimte shell?
The third last shell. What a mouthful!
What is the first element that need a third shell?
It is sodium Chlorine is the first element that needs a third shell.
How many electrons does sulfur have in its third electron shell?
Sulfur has six electrons in its third electron shell.
What group of elements already has a full shell?
Noble gases already has full valence shell
Why are Sodium and Chlorine not stable elements?
Sodium and Chlorine are chemically unstable due to the amount of electrons each has in the outer shells (also known as layers) of their atoms. Sodium has 11 electrons. First shell: 2 electrons Second shell: 8 electrons Third shell: 1 electron As the number of electrons in the last shell is not 8 and as the shell is not full Sodium is chemically unstable. Chlorine has 17 electrons. They are arranged like this: First shell: 2 electrons Second shell: 8 electrons Third shell: 7 electrons The number of electrons in the last shell is not 8, and the shell is not full, and thus, chlorine is chemically unstable. To give an example of a chemically stable element, Argon has 8 atoms in its last shell, which is why it is chemically stable and therefore does not react with any element.
You have 2 electrons in the first shell 8 in the second shell and 6 in he third shell?
Sulfur
What has 2 electrons in the first shell 8 in the secod shell and 6 in the third shell?
Sulfa.
How many additional valence shells does chlorine need to have a full valence shell?
11 electrons makes the third energy level complete. One

When full the innermost electron shell of argon contains how many electrons?
there are 2 completely full shells in argon. Argon= 18 electrons. 2 first shell 8 second shell (full) and 8 third shell (full)
