... Since the time of Rutherford (1911) physicists and chemists commonly believed that with no electric field, the nucleus of an atom is at the centre of the electron cloud, atoms do not have permanent electric dipole moment (EDM), so that there is no polar atom in nature. In the fact, the idea is untes ...

... An element is a substance that cannot be broken down into simpler substances by chemical means. A molecule is the smallest unit of a substance that behaves like the substance. A compound is a substance made up of atoms of different elements. Every compound differs from the elements that it contains. ...

Introduction to the Physics of Matter
... Experimental resolution is typically limited by the resolution of the monochromator, noise in the photon detector, inhomogeneities in the sample or in some external field applied to it. Experimental broadening is usually generated by several random concurrent effects, and determines therefore a Gaus ...
