That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
No, elemental Bromine or Br2 is not an ion
The sodium atom gives an electron to the chlorine atom to make the sodium and chloride ions respectively. Then they form ionic bonds forming sodium chloride.
Cl has a tendency to gin electrons in a reaction, this is due to the fact that it has 7 electrons already, its much easier for chlorine to gain one more electron to have a full shell than to lose 7 and have a full shell.
The sodium atom, Na, is ionized, giving it's electron to the chlorine, Cl. Therefore, one electron is transferred from the sodium to the chlorine, forming Na+ and Cl- ions and an ionic bond.
The electrons do not attract each other. The single valence electron of a sodium atom is given up to a chlorine atom. This results in the sodium atom forming a positive sodium ion, and the chlorine atom forming a negative chloride ion. The oppositely charged ions form an electrostatic attraction, which forms the neutral ionic compound of sodium chloride.
Chlorine will gain one electron when forming an ion. Chlorine therefore fills its valence electron shell with 8 e-. Chlorine usually bonds with group 1 metals, like Na (Sodium).
negative

Chlorine is very electronegative and pulls on the hydrogen's single electron, forming a positive end where the Hydrogen atom is, and a negative charge where the Chlorine is. This is because the Chlorine pulls much harder on the electron than Hydrogen does.
Potassium and chlorine are the only two that can.
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
The chloride ion is an anion (Cl-).

Sodium Chloride does not have free electrons normally, Sodium with electron arrangement: 2,8,1 and Chlorine with electron arrangement: 2,8,7 When they react Sodium ionises to 2,8 ( Ne) Chlorine gains the free electron to ionise to 2,8,8 (Ar) Forming Sodium Chloride or Na+CL-
