CN, the coordination number, which is the number of closest neighbors to which an atom is bonded. APF, the atomic packing factor, which is the fraction of the volume of the cell actually occupied by the hard spheres. Show crystalographic planes [1 0 2], [2 2 1], [6 3 2], [10 1 0] Crystalographic Planes [1 0 2].
The reason is the electronic devices divert your attention and also cause strains while reading eBooks. The chapter wise segregation has been done to align with contemporary competitive examination pattern. It has been ensured from made easy team to have broad coverage of subjects at chapter level.
