Define a) diamagnetism b) space lattic

Answer»

a) Diamagnetic substances are those which have a tendency to move from stronger part to the weaker part of the externalmagnetic field. We can also say that the diamagnetic substances get repelled by a magnet.

b) The position of atoms, molecules, or ions in a solid crystal, relative to one other in space, is usually designated by points. Such a representation is calledspace lattice.Thus, we define thespace lattice as an array of points showing how molecules, atoms or ions are arranged at different sites in three-dimensional spaces
