This depends on the model used and thoerys applied.
Using the Lewis Model it is 8, although certain molecules can "Expand their octet" and become hypervalent.
IF you are looking at the subshell model (used at university level) it is 14 in the lanthanium series and actinium series.
Sulphur has 6 electrons in its outermost shell.
4.See the Related Questions for how to determine the number of electrons in the outermost shell of all the elements!
The chemical properties of an atom depend on the number of electrons in its outermost shell, known as the valence electrons. These electrons determine how atoms interact with other atoms to form chemical bonds.
Atoms can have a maximum of 8 electrons in their outermost energy level, except hydrogen and helium which can have a maximum of 2 electrons. The number of electrons in the outer shell determines an atom's chemical properties and reactivity.
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.

The maximum number of valence electrons an element can have is 8. This is because the outermost energy level, or valence shell, of an atom can hold a maximum of 8 electrons. Exceptions to this rule can occur for elements that can have more than 8 electrons in their valence shell through the process of expanded octet.
The maximum number of electrons that can be accommodated in the outermost shell of an atom is determined by the formula (2n^2), where (n) is the principal quantum number of that shell. For the first shell ((n=1)), it can hold 2 electrons; for the second shell ((n=2)), it can hold 8 electrons; for the third shell ((n=3)), it can hold 18 electrons; and for the fourth shell ((n=4)), it can hold 32 electrons. However, for practical purposes regarding chemical bonding, the outermost shell is often considered full with 8 electrons, following the octet rule.

2 electrons are found in the first electron shell.

The chemical properties of an atom depend on the number of electrons in its outermost shell, known as the valence electrons. These electrons determine how atoms interact with other atoms to form chemical bonds.
The maximum number of electrons that a representative element can possess is 8. This is because the outermost electron shell of these elements can hold a maximum of 8 electrons in order to achieve a stable electron configuration.
There are 3 electrons in the outermost shell of an aluminum atom, as it has atomic number 13.
In order for it to be a cation, the maximum number of electrons it can have is one less than the number of protons. I don't know what "needed" means in this context, but hopefully that answers what you were trying to ask.
