Explain why vanadium (radius=134 pm) and copper (radius=128 pm) have nearly identical atomic radii, even though the atomic number of copper is about 25% higher than that of vanadium.
what would you predict about the relative densities of these two metals? look up the densities in a reference book, periodic table, or on the web.
are your predictions correct?
