Assuming the following metals all have the same unit cell structure,which of the following would be expected to have the highest density: Sc,Ti,Mn,or Co?

Question

Quizplus · Accepted Answer

The atomic radius increases as we move from right to left and from top to bottom in the periodic table. Therefore, Sc is expected to have the largest atomic radius among the given options, while Co is expected to have the smallest atomic radius. Since all the metals have the same unit cell structure, the one with the smallest atomic radius (Co) would pack the most atoms in a given volume, leading to the highest density. Therefore, Co is expected to have the highest density among the given options.
