Calculation of Density of a Cubic Crystal from its Edge Length
Calculation of Density of a Cubic Crystal from its Edge Length. The edge length of a cubic crystal can be obtained from X-ray studies and knowing the crystal structure possessed by it so that the number of particles per unit cellh..
Unit cell
The smallest three-dimensional portion of a complete space lattice, which when repeated over and again in different directions produces the complete space lattice. The size and shape of a unit cell is determined by the lengths of the edges of the unit..
