The correct statement describing what happens to Li and Cl atoms when they bond is Li loses 1 valence electron and becomes a positive ion, Cl gains 1 valence electron and becomes a negative ion. Option B is correct.
Lithium (Li) tends to lose one valence electron to form a stable, noble gas electron configuration after the creation of an ionic bond with chlorine (Cl), turning into a positive ion (Li⁺). In the meantime, chlorine tends to become a negative ion (Cl⁻) by gaining one valence electron to form a stable, noble gas electron configuration.
Therefore, Option B is correct.
The complete option are :
Which statement correctly describes what happens to Li and Cl atoms when they bond? a . Li loses 1 valence electron and becomes a negative ion, Cl gains 1 valence electron and becomes a positive ion . b. loses 1 valence electron and becomes a positive ion, gains 1 valence electron and becomes a negative ion. . Li gains 1 valence electron and becomes a negative ion, loses 1 valence electron and becomes a positive ion. d . Li gains 1 valence electron and becomes a positive ion, loses 1 valence electron and becomes a negative ion.
