Question
Give the significance of a 'lattice point'.
Solution
(i) Each point in a lattice is called lattice point or lattice side.
(ii) Each point in a crystal lattice represents one constituent particle which may be an atom, a molecule or an ion.
(iii) Every lattice point has identical surroundings except those which are on the surface or corner of a crystal.
(iv) If a line is drawn by joining two lattice points, it would pass through a series of similar points at regular intervals.
(v) Lattice points are joined by straight lines to bring out the geometry of the lattice. These lines do not represent chemical bond.
