The diagram shows a simple model of metallic structure. The metal ions are shown as tiny spheres, packed closely together in a regular pattern.

IN a paper on the “foam structure” of metals, in The international Journal of Metallography (iii., i), Prof. Quincke gives a summary of the conclusions which he states as the result of ...

A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised ...
