A certain metal crystallizes in a body centered cubic unit cell with an edge length of 310 pm. What is the length in Angstroms of the unit cell diagonal that passes through the atom?
Radius = 310 pm
so the diagonal length = 4 * r
= 4*310 pm
= 1240 pm
now lets convert pm to angstrom
1240 pm * 0.010 A / 1 pm = 12.4 A
So the length of the diagonal is 12.4 Angstrom
