Question

If a single displacement reaction has the general formula of A + BX -> AX + B and X

on the reactants side of the equation is in group 17, what is happening to the

valence electrons in product B?

Answer 1

In a single displacement reaction, the valence electrons in product B remain the same.

Step-by-step explanation:

In a single displacement reaction, an element A displaces element B from its compound BX to form a new compound AX and release element B. Since the X element in the compound BX is from group 17, it means it belongs to the halogen family. Halogens, such as chlorine and bromine, have seven valence electrons. When element B is displaced by element A in the reaction, the valence electrons in B will remain the same because the compound AX will not affect the number of valence electrons in element B.
