What is lattice |
|
Answer» Lattice is an arrangement in space of isolated points (lattice points) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal.A crystal lattice is the arrangement of these atoms, or groups of atoms, in a crystal. These atoms or groups of atoms are commonly referred to as points within a crystal lattice site. Thus, think of a crystal lattice site as containing a series of points arranged in a specific pattern with high symmetry. Note that these points don\'t tell you the position of an atom in a crystal. They are simply points \'in space\' oriented in such a way to build a lattice structure. Lactic acid is present in curd acid present in curd |
