3. Beryllium (Be) is an HCP structure with a=0.22858 nm and c=0.35842 nm. The atomic radius is 0.1143 nm, the density is 1.848 g/cm3, and the atomic mass is 9.01 g/mol. In this case, find (a) the number of atoms in the single crystal and (b) the atomic filling rate of the unit crystal.
Given that the salt, Potassium Bromide (KBr), forms the pictured rock salt structure and in that
structure the K* and Br ions touch along the family of directions, calculate the atomic packing factor
(APF) and theoretical density (p) in [g/cm'). Then answer the concept question.
lonic radius: K* = 0.138 nm; Br = 0.196 nm
Atomic Weight: K = 39.1 g/mol; Br = 79.9 g/mol
APF =
9 /cm²
Identify the type of ceramic defect that occurs where a pair of
K* and Br ions goes missing from the lattice.
Circle the correct option:
a) Frenkel defect
b) Schottky defect
