In which set do all elements tend to form anions in binary ionic compounds In which set do all elements tend to form anions in binary ionic compounds a( Ba Cu Sn b( Se F Cl c(Rb Sn S d( P As Sb?

Set c (Rb, Sn, S) tends to form anions in binary ionic compounds. Rb is a metal that tends to lose an electron to form a cation, while Sn and S are nonmetals that tend to gain electrons to form anions.
