It would be the symbol Cl with 8 dots around it (4 pairs).
Cl-
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.
The electronic arrangement of chlorine is 2, 8, 7. This means that chlorine has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its outermost energy level.
Two electrons in the first level, 8 in the second, 7 in the third. The electron configuration notation is: 1s22s22p63s23p5, or [Ne]3s23p5. Incidentally, this is the same arrangement as in chlorine-37, which is chlorine's only other isotope.
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.

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.
A chlorine atom has 7 valence electrons because it is in Group 17 of the periodic table. The electron configuration Ne3s23p5 represents the arrangement of electrons in the atom, with the 3s and 3p sublevels containing a total of 5 electrons.
1 electron
The species 35Cl1 refers to a chlorine atom with 17 electrons because the atomic number of chlorine is 17.
Two electrons in the first level, 8 in the second, 7 in the third. The electron configuration notation is: 1s22s22p63s23p5, or [Ne]3s23p5. Incidentally, this is the same arrangement as in chlorine-37, which is chlorine's only other isotope.

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.
Chlorine has 17 electrons. 7 of its electrons are valence electrons.
