Explanation / Answer

a. Metallic radius is defined as one-half of the distance between the two adjacent metal ions in the metallic lattice. This radius depends on the following factors:-

THus the metallic radius of Ag is 3.06/2 = 1.53 Angstroms.

b) Yes, the higher the pressure, the tighter the atoms are packed together. When the pressure is removed, the atoms return back to their ideal separation distance.This is explained on the basis of the Bulk modulus which is the direct repercussion of the contraction of the atoms (neghbouring) at the applied external pressure.
