Chlorine has a valency of one because it has seven valence electrons in its outer shell. By gaining one electron, chlorine can achieve a stable electron configuration similar to that of a noble gas, specifically argon, which has a full outer shell with eight electrons.

What is the valency of AlCl3?

The valency of AlCl3 is 3. This is because aluminium (Al) has a valency of +3 and each chlorine atom (Cl) has a valency of -1, so it takes 3 chlorine atoms to balance the charge of one aluminium atom.


Valency of chlorine?

Chlorine has a valency of 1, meaning it tends to gain one electron to achieve a full outer electron shell. This electron configuration allows chlorine to form a stable chloride ion, Cl-.


What is the valency of an element sodium chloride?

Sodium chloride is composed of sodium (Na) and chlorine (Cl). Sodium has a valency of +1, while chlorine has a valency of -1. In sodium chloride, sodium donates its electron to chlorine, forming an ionic bond with a valency of +1 for sodium and -1 for chlorine.


Why are fluorine and chlorine in the same group?

Both have one electron vacancy in their valency orbital.


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.


Does chlorine has positive or negative valency?

Negative.


What is the valency of Cl in AlCl3?

In aluminum chloride (AlCl3), the valency of chlorine (Cl) is -1. Each chlorine atom gains one electron to achieve a stable electron configuration, resulting in a negative charge. Since there are three chlorine atoms in AlCl3, they collectively balance the +3 charge of aluminum (Al), which has a valency of +3. Thus, the overall compound is electrically neutral.


Can a chlorine atom be bonded to two other atoms?

Since chlorine has a valency of 1 only, it can bond only wit one atom at a time


What is the valency of tetrachloride?

i think 4 is the valency of tetrachloride


What is valency of 17 element?

This is Cl, chlorine, with multiple valency values: -1, +1, +3, +5, +7


What is the valency of phosphorus trichloride?

The valency of phosphorus trichloride is 3. Phosphorus forms three covalent bonds with chlorine atoms in this compound, resulting in a valency of 3.


Why valency of chlorine is 1?

Chlorine typically has a valency of 1 because it needs to gain one electron to complete its outer electron shell and achieve a stable electron configuration similar to a noble gas. By gaining one electron, chlorine forms a chloride ion with a 1- charge, allowing it to achieve a stable electron configuration and become more chemically stable.
