A Nobel gas, or an atom with a filled valance shell. In Nobel gas configuration.
8 electrons on the outer shell
8 electrons.

Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
A full outer ring, or valence shell, has 8 electrons, except for helium, which has 2 electrons.
8 electrons on the outer shell
8 electrons.
No atom can hold 18 electrons in its outer energy shell - there is the valence rule, stating that the maximum for the outer shell is 8 electrons.

Electrons per shell in astatine: 2, 8, 18, 32, 18, 7.
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.

YES!
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.

8. But if it is the first shell it can only be 2.
