    Notes: [Auszug] FOLLOWING J. J. Thomson, Kossel, and others, it can be shown that a large number of observed facts about co-ordination compounds can be explained on the assumption that these groups are held by purely electrostatic forces to the central atom. Grimm has been able to calculate the heat of ...

    Notes: [Auszug] ACCORDING to Bohr's theory of atomic structure, the colour shown by compounds of elements belonging to the transition groups is ascribed to the presence of incomplete inner shells in them, and to the small difference in the binding energy of an electron attached to the outer valency and the ...

    Notes: [Auszug] A GROWING plant bends towards light; this is true, not only of the main stem, but also of its branches and attached leaves and leaflets. This movement in response is described as the tropic effect of light. Growth itself is modified by the action of light: two different effects depending on the ...
