Question

when chlorine gains one electron in its inter most cell it is cnvented to​

Answer 1

Answer:

Chlorine's electronegativity is 3.5 and to fulfill it's octet and to achieve stability Chlorine attracts electron towards it.By gaining an electron Chlorine achieves Nobel gas configuration (Ar-Argon).

Whereas Sodium's electronegativity is 0.9 and to achieve stability it loses anot electron from it's outermost orbit.By losing an electton Sodium achieves Nobel gas configuration (Ne-Neon).

Electronic Configuration of Chlorine and Sodium before gaining and losing an electron

Cl - 1s^2 2s^2 2p^6 3s^2 3p^5

Na - 1s^2 2s^2 2p^6 3s^1

and after gaining and losing an electron

Cl - 1s^2 2s^2 2p^6 3s^2 3p^6.

Na - 1s^2 2s^2 2p^6.
