X-ray studies show that the packing of atoms in a crystal of a metal is found to be in layer such that starting from any layer, every fourth layer is exactly identical. The density of the metal is found to be 19.4 g cm–3 and its atomic mass is 197 u.
Assuming the metal atom to be spherical, its radius will be
- 103.5 pm.
- 143.9 pm.
- 146.5 pm.
- 267.8 pm.
Answer
(B) 143.9 pm.
