What is the electron configuration of a chlorine ion in a compound of BeCl2?

In a compound like BeCl2, chlorine typically exists as a chloride ion (Cl⁻) after gaining one electron. The electron configuration of a neutral chlorine atom is 1s² 2s² 2p⁶ 3s² 3p⁵. After gaining an electron, the configuration for the chloride ion becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is the same as that of argon, indicating that the chloride ion has a stable noble gas configuration.


What is the valency of chloride ion in chlorine molecule?

The valency of a chloride ion in a chlorine molecule is -1. Each chloride ion gains one electron to fill its outer shell and achieve a stable electron configuration.


What is the chloride ion and chlorine atom electron configuration?

The chloride ion (Cl-) has the same electron configuration as argon (1s2 2s2 2p6 3s2 3p6) because it has gained an electron compared to a neutral chlorine atom. The chlorine atom has an electron configuration of 1s2 2s2 2p6 3s2 3p5.


Why chlorine forms a negative ion?

Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.


Chlorine forms a 1- ion How many electrons does a chloride ion have?

A chloride ion has gained one electron to achieve a full outer shell and achieve a stable electron configuration. Therefore, a chloride ion has 18 electrons.


What is the ground-state electron configuration of the chloride ion Cl?

What is the electronic structure of a chloride ion?

A chloride ion (Cl-) has an electron configuration of 1s2 2s2 2p6 3s2 3p6, which is the same as that of argon. It has gained one electron to achieve a full outer shell and a stable octet configuration.


What type of ion might chlorine form?

Chlorine can form a chloride ion with a -1 charge by gaining one electron to achieve a stable electron configuration.


What is the noble gas electron configuration of chloride ion?

The noble gas electron configuration of chloride ion (Cl-) is [Ne]3s^23p^6, which is equivalent to the electron configuration of argon. This means that chloride has gained an extra electron compared to neutral chlorine, resulting in a full outer electron shell and a stable, closed-shell configuration.


What is atomic core for chloride ion?

The atomic core for a chloride ion consists of 17 protons in the nucleus, giving the ion a net charge of -1 to balance the single electron in its outer shell. This configuration gives it the same electron configuration as a noble gas (argon), making it stable.


Which ion has the same electron configuration as argon?

The chloride ion (Cl-) has the same electron configuration as argon, which is 1s2 2s2 2p6 3s2 3p6. This is because the chloride ion has gained an extra electron compared to argon, giving it a full outer electron shell.
