A) Their metallic character varies greatly.
B) There are large differences in their abilities to form strong pi bonds.
C) There are large differences in their ionization energies.
D) There are large differences in their electronegativities.
E) none of these

Question

Quizplus · Accepted Answer

The stability of a bond is related to its ability to form strong pi bonds, which are formed by overlapping of atomic orbitals. C⎯C, N⎯N, and O⎯O can form strong pi bonds due to their smaller atomic size and higher electronegativity. On the other hand, Si⎯Si, P⎯P, and S⎯S have larger atomic size and lower electronegativity, which results in weaker pi bond formation and less stability.
