The most stable atoms/ions have 8 electrons in their outermost shell.
They share their valence electrons
Stable.
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
Noble gas
2.
8 electrons
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
it is called complete or completely stable
yes
Group 8
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.
hydrogen, helium, lithium, and beryllium
