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.
It would be the symbol Cl with 8 dots around it (4 pairs).
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.

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).
The electron configuration of chlorine is 1s^2 2s^2 2p^6 3s^2 3p^5. This arrangement shows how the 17 electrons in a neutral chlorine atom are distributed among its various atomic orbitals.
