The Lewis theory predicts that the formula for a compound made of sodium and fluorine is NaF.

Question

Quizplus · Accepted Answer

The Lewis theory states that atoms tend to gain or lose electrons in order to obtain a stable electron configuration, and that atoms with a tendency to lose electrons (such as sodium) will form positive ions, while atoms with a tendency to gain electrons (such as fluorine) will form negative ions. Therefore, when sodium and fluorine react, sodium loses one electron to become a positive ion and fluorine gains one electron to become a negative ion, resulting in the formation of an ionic compound with the formula NaF.
