What is the valence electron configuration for the Group 3A elements? How does metallic character change as one goes down this group? How are boron and aluminum different?
Answer to relevant QuestionsWhat are three-centered bonds? The following illustration shows the orbitals used to form the bonds in carbon dioxide. Each color represents a different orbital. Label each or-bital, draw the Lewis structure for carbon dioxide, and explain how the ...The resistivity (a measure of electrical resistance) of graphite is (0.4 to 5.0) × 10-4 ohm . cm in the basal plane. (The basal plane is the plane of the six- membered rings of carbon atoms.) The resistivity is 0.2 to 1.0 ...Use bond energies (Table 13.6) to show that the pre-ferred products for the decomposition of N2O3 are NO2 and NO rather than O2 and N2O. (The N–O single-bond energy is 201 kJ/ mol.) (Hint: Consider the reaction ...White phosphorus is much more reactive than black or red phosphorus. Explain.
