we are discussing here 12th class chemistry question give the significance of a lattice point ?
answer : as we know that every crystal lattice is made up of basic constituent particles which may be atoms , molecules and ions , in any crystal lattice these particles are arranged in some arrangements. The position of any constituent particle can be defined by lattice point.
In short we can say that lattice point shows or give identification to the position of any constituent particles found in that particular crystal lattice.
Now question occurs why some arrangement is required in any crystal lattice ?
To give definite size and shape to any crystal solid the arrangement of lattice point is necessary , according to arrangement of lattice points , the crystal solid gain it’s shape and size.
