What we call the K shell is only part of space nearest the nucleus in which the probability for an electron's being found is the biggest. In that shell, the energy of electrons is the lowest, and that is why electrons will spend most time there, because only two electrons can be in that position at the same time, while the rest of them have to be placed in higher shells.
The outer shell of an atom is the valence shell, which contains the valence electrons.
An oxygen atom has six (6) electrons in its outer shell.
A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.

The valence shell is the outermost shell...and an atom can only have one outer shell.
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
