What is the atomic radius of polonium if it crystallises in a simple cubic structure with edge length of unit cell 336 pm ?

Options

  1. A84 pm
  2. B168 pm
  3. C234 pm
  4. D336 pm

Correct answer

B. 168 pm

Step-by-step solution

For simple cubic structure, aligned & a=2 r & a= Edge length of unit cell & r= radius of atoms & 336=2 r & r=168 pm aligned
