Atoms of metals x, y and z form face-centred cubic (fcc) unit cell of edge length Lx, body-centred cubic (bcc) unit cell of edge length Ly, and simple cubic unit cell of edge length Lz, respectively.
If ${\mathrm{r}}_{\mathrm{z}}=\frac{\sqrt{3}}{2}\mathrm{\hspace{0.17em}\hspace{0.17em}}{\mathrm{r}}_{\mathrm{y}};{\mathrm{r}}_{\mathrm{y}}=\frac{8}{\sqrt{3}}\mathrm{\hspace{0.17em}}{\mathrm{r}}_{\mathrm{x}};{\mathrm{M}}_{\mathrm{z}}=\frac{3}{2}{\mathrm{M}}_{\mathrm{y}}\mathrm{\hspace{0.17em}}\mathrm{and}\mathrm{\hspace{0.17em}}{\mathrm{M}}_{\mathrm{z}}=3\mathrm{\hspace{0.17em}}{\mathrm{M}}_{\mathrm{x}}$  , then the correct statement(s) is(are):
[Given: M_x, M_y, and M_z are molar masses of metals x, y, and z, respectively. r_x, r_y, and r_z are atomic radii of metals x, y, and z, respectively.]
