This depends which shell it is up to. Helium has a full shell and it only has 2 electrons. Neon then, still with a full outer shell has 8 on the full outer shell with 2 inside those 8.
This keeps changing as you go up. I do believe the amount of electrons on the outer shell goes 2, 8, 8, 18, 18, 32. Those apply to the stable elements (in order) Helium, Neon, Argon, Krypton, Xenon and Radon.
Those numbers apply to the outside shell, please note all the shells below that outside one still exist and are still full.
if the rings are filled up the atom is stable. the first ring holds four the second ring holds 8 i believe.
Eight valence electrons to be stable.
Most elements need 8 electrons in their valence shells.
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons
Only when their outer shell is saturated>>>>>>>>>>>>
It'll have to lose two to have a stable octet.
silicon's atomic number is 14 so, its electron configuration is 2.8.4, the third shell needs 4 more electrons to make it 8 and to become stable. ---> so the answer is 4.
8 to make it stable and least reactive.
The number depends on what will fill the outer shell. It can be 2 or 8.
Most elements need 8 electrons in their valence shells.
The most stable atoms/ions have 8 electrons in their outermost shell.

Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.

you would need a full outer shell so 8
