Chlorine's atomic number is 17. Thus, neutral chlorine has 17 protons and 17 electrons. Its total configuration is 1s2 2s2 2p6 3s2 3p5, so its valence configuration is 3s2 3p5.
Halogen atoms typically gain one electron when they react to achieve a stable electron configuration, forming a halide ion with a charge of -1. For example, chlorine (Cl) gains one electron to become Cl-.
Cl and F
Sodium chloride is neutral; only elements have an electronegativity.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
Li loses one electrons. Cl gains the electron.
In a Cl-Cl molecule, the atoms are sharing 2 electrons, forming a single covalent bond. Each chlorine atom contributes 1 electron to the bond, resulting in a total of 2 shared electrons between the two atoms.
Li atom donates one electron to a Cl atom when Li+Cl- is to be formed as ionic compound (salt):Li --> e- + Li+Cl + e- --> Cl--------------- +Li + Cl --> LiCl (or Li+Cl-)
18. Cl=17 Na= 11
Chlorine (Cl) will typically form a chloride ion (Cl-) by gaining one electron, achieving a full outer electron shell.
The anion of chloride (Cl⁻) has 18 electrons, as it has gained one electron to achieve a stable electron configuration. Chloride has 17 electrons in its neutral state, but when it gains an electron, it becomes Cl⁻ with 18 electrons.

Chlorine (Cl) has 17 electrons in its shells.
Halogen atoms typically gain one electron when they react to achieve a stable electron configuration, forming a halide ion with a charge of -1. For example, chlorine (Cl) gains one electron to become Cl-.
Yes, the Cl- ion is larger than the Cl atom because the addition of an extra electron leads to an increase in electron-electron repulsions, which causes the electron cloud to expand. This results in the formation of an anion (Cl-) that is larger in size compared to the neutral atom (Cl).

Cl and F
No, Cl (chlorine) and Ar (argon) do not have the same electron configuration. Cl has the electron configuration 1s2 2s2 2p6 3s2 3p5, while Ar has the electron configuration 1s2 2s2 2p6 3s2 3p6. Ar has a full outer shell, making it a noble gas, while Cl is a halogen with one electron short of a full outer shell.
