Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn't actually much to work out. But when elements lo...

A PRECISE measure of the charge on an atom in a molecule is provided by calculating the number of electrons within a sphere of covalent radius using molecular wavefunctions. The results for alkyl substitution suggest that the simple qualitative ideas of the inductive effect may be less simple ...
Electric charge, basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field . Electric charge, which can be positive or negative, occurs in discrete natural units and is neit
【题目】翻译一下可以吗1.An atom is made up of positi ve charges (protons),neutral charges (neutrons)an d negative charges (electrons). T he protons a n d neutrons are foun d within the nucleus of an atom,while we learnt in P08 Curious glow that the electrons are foun d in ...
This leads to Laplace's equation on a five-dimensional hypersphere in the six-dimensional Euclidean manifold. It is shown that an additional quantum number can be identified with the charge of the nucleus. The energy levels of the atom are degenerate with respect to the additional quantum ...

The concept of a polar or “ferroelectric” metal was first proposed by Anderson and Blount in 1960s.1They considered a continuous structural-phase transition breaking the inversion symmetry and leading to the appearance of a polar axis in a metal. This appears counter-intuitive since one expects...
