Calculate the radius of a tantalum (Ta) atom, given that Ta has a BBC crystal structure, a density of 16.6g/cm³, and an atomic weight of 180.9 g/mol.

Answer 1

Please some one help me on this, I don't have the answer myself

Answer 2

16.6 g/cm^3 * 1mole/180.9g * 6.023*10^23 atoms/mole = 5.535*10^22 atoms/cm^3

The article below shows how to relate the atomic radius to the BCC packing structure.
