Question

true /false valency of chloride ion is 1
​

Answer 1

Answer:

The atomic number of chlorine is 17 (Z=17). The electronic configuration of chlorine can be written as 2, 8, 7. ... Therefore, valence electron in chlorine is 7 and it needs to gain 1 electron from the outermost orbit to attain octet. Hence, the valency of chlorine is 1.

Answer 2

Answer:

The Atomic number of chlorine I.e. Cl is 17 and it's electronic configuration is 2,8,7. Since it has 7 valence electrons in it's outermost shell and it needs one electron to complete it's octet. Hence, it's valency is -1.
