Cl--Cl with three lone pairs around each
The electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
Sodium reacts with chlorine gas because sodium wants to donate its electron to chlorine to achieve a stable electron configuration, and chlorine wants to gain an electron to also become stable. This electron transfer results in the formation of ionic bonds between sodium and chlorine atoms, leading to the creation of sodium chloride (table salt).
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
In a molecule of hydrogen chloride (HCl), the hydrogen atom attains a noble gas electron structure by sharing its electron with the chlorine atom, which attains a noble gas structure through the addition of the shared electron. The resulting electron structure mimics that of a noble gas (helium for hydrogen and argon for chlorine), fulfilling the octet rule for both atoms.
It does so because it gains an extra electron in order to attain a noble gas state, i.e. in order to contain the same # of electrons as a noble gas. in the case of Chlorine, that gas is Argon which has an atomic # of 18, therefor having 18 electrons. Chlorine has an atomic # of 17. In order to be monoatomic with Argon, it gains an extra electron to have a total of 18 electrons. Since it now has 1 more electron than protons, it's charge is -1. Therefore, it is written as Cl-.
We can logically walk through this. Hydrogen has 1 proton, and 1 electron. Chlorine has 17. If these were to combine stably, Argon would be made. Argon is a noble gas and therefore has 8 full valence electron slots.
The electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
Gain an electron.
Chlorine need one extra negatively charged electron to be a noble gas.
Sodium reacts with chlorine gas because sodium wants to donate its electron to chlorine to achieve a stable electron configuration, and chlorine wants to gain an electron to also become stable. This electron transfer results in the formation of ionic bonds between sodium and chlorine atoms, leading to the creation of sodium chloride (table salt).
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
No, chlorine (Cl) does not have a noble gas electronic configuration. It has the electron configuration [Ne]3s^2 3p^5, which is one electron away from achieving a stable, noble gas configuration like argon (Ar).
Chlorine will have a noble gas configuration by accepting one electron from a sodium atom to form an ionic bond. This results in chlorine gaining a full outer electron shell, similar to the noble gas configuration of argon.
Chlorine Electron configuration - [Ne] 3s 2 3p 5
He :The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
The ionic charge for chlorine gas molecules is 0. Chlorine gas is composed of Cl2 molecules, where each chlorine atom shares an electron pair with the other, resulting in a covalent bond and no net charge.
