When there is a large excess of mercury, it is possible to form compounds containing the Hg22+Hg22+ ion. All mercury compounds are toxic, and it is necessary to exercise great care in their synthesis. Amalgams An amalgam is an alloy of mercury with one or more other metals. This is ...
Ions of the metals, especially the transition metals, are likely to form complexes. Many of these compounds are highly colored. In the remainder of this chapter, we will consider the structure and bonding of these remarkable compounds.Figure 1. Metal ions that contain partially filled d subshell...
‘from Delbrück’s general picture of the hereditary substance it emerges that living matter, while not eluding the laws of physics as established up to date, is likely to involve hitherto unknown ‘other laws of physics. Once they have been found, they will form just as integral a part ...
