"An ion with a single negative charge..........."An ion with a single negative charge...........

Explanation:

And we can represent such ion formation by the reaction:

1/2X_2 + e^(-) rarr X^(-)12X2+eX

Such reduction fills the valence shell of the halide to give an electronic count of 88; the halide ion, X^-X, is reasonably stable.
