    Metals with body‑centered cubic (bcc) structures, such as tantalum, are not closely packed. If they were to change to a cubic close‑packed (ccp) structure (under pressure, for instance), their densities would be greater. What would the density of tantalum be if its structure were ccp rather than bcc? Its actual density is 16.7 g⋅cm−316.7 g⋅cm−3 .
