Concept explainers
Interpretation: The reason for the difference that at low temperature, the unit cell of calcium metal exhibits FCC form and at high temperature, the unit cell of calcium metal exhibits BCC form has to be stated.
Concept introduction: Body centered cubic cell form consists of one lattice point at the center with eight corner lattice points.
Face centered cubic cell form consists of lattice point on all the six faces of the cubic unit cell with eight corner lattice points.
To determine: The reason for the difference that at low temperature, the unit cell of calcium metal exhibits FCC form and at high temperature, the unit cell of calcium metal exhibits BCC form.
