Chlorines electron configuration can be described in a few different ways - it also depends on whether you are talking about chlorine gas or chlorine the atom.
For the atom - chlorine has 17 electrons. Simply describes the electron arrange could be called 2, 8, 7 (where the number represents the # of electrons in each shell.
From the more advanced atomic orbital theory - chlorines electron configuration could be notated as such: 1s2 2s2 2p6 3s2 3p5 (where the last number in each is superscript).
For chlorine gas, the electron configuration is described using molecular orbital theory (university level) as such:
non-valence electrons are ignored - since they are too far separated to combine their wavefunctions meaningfully - so we only consider valence electrons (3rd shell ie 3s and 3p in this case)
σ3s2 σ3s*2 σ3p2 π3p4 π3p*4
Chlorine needs to gain one electron to achieve the same electron arrangement as neon, which has a stable octet (eight valence electrons). By gaining one electron, chlorine will have a full outer shell with eight electrons, resembling the electron arrangement of neon.
The electron arrangement in an ion of chlorine will be similar to argon because both chlorine (Cl) and argon (Ar) are in the same period (row) of the periodic table. Neon (Ne) is in a different period and has a different electron arrangement.
No element has the exact same election arrangement as another element. However ion can have the same election arrangement as another element. For example Chloride (Cl-) has the same configuration as Argon, and Potassium (I) (K+) also has the same configuration as argon.
Sulfur has an electron configuration of 2-8-6, with two electrons in the first energy level, eight in the second, and six in the third. Chlorine has an electron configuration of 2-8-7, with seven electrons in the third energy level. This difference in electron arrangement affects their chemical properties and reactivity.
Sodium loses an electron to become a positively charged ion (Na+), while chlorine gains an electron to become a negatively charged ion (Cl-). This results in the formation of an ionic bond between sodium and chlorine ions to create sodium chloride.

When a chlorine atom becomes a chlorine ion, it gains an electron to achieve a full outer electron shell. This results in the electron arrangement changing from 2,8,7 to 2,8,8, making it a negatively charged ion.
A chlorine ion with a stable arrangement of eight valence electrons is called a chloride ion (Cl-). It achieves this stable arrangement by gaining one electron from another atom to fill its outermost electron shell.

A chlorine atom would need to lose one electron to have a stable electron arrangement like neon, which has a full valence shell of electrons. Chlorine normally has 7 electrons, but by losing one electron, it will have 8 electrons in its outer shell, achieving stability.
The electron-domain geometry of ClO4- is tetrahedral. It has four electron domains around the central chlorine atom, resulting in a tetrahedral arrangement.
The electron configuration of chlorine-35 and chlorine-37 is the same. Chlorine has an atomic number of 17, with the electron configuration of 1s2 2s2 2p6 3s2 3p5. The isotopes differ only in their number of neutrons, not in their electron arrangement.
It would be the symbol Cl with 8 dots around it (4 pairs).
