Question

in a binary ionic compound, the electrons are
a shared
b transferred from the metal to the nonmetal
c transferred from the nonmetal to the metal

Explanation:

Binary ionic compounds form between metals (which tend to lose electrons) and nonmetals (which tend to gain electrons). Electrons are transferred, not shared (sharing occurs in covalent bonds). Metals give electrons to nonmetals to form charged ions that attract each other.

Answer:

B. transferred from the metal to the nonmetal
