allotropy (Noun)
A property, exhibited by some elements of existing in multiple forms with different atomic structures.

allotropy (n.)
The property of existing in two or more conditions which are distinct in their physical or chemical relations.

allotropy
al-lot′ro-pi, n. the property in some elements, as carbon, of existing in more than one form.—adj. Allot′ropic. [Gr.; allos, another, and tropos, form.]

allotropy
The power of existing in several modifications possessed by some substances, notably by chemical elements. Instances of the allotropic state are found in carbon which exists as charcoal, as graphite (plumbago or black lead), and as the diamond. All three are the same elemental substance, although differing in every physical and electrical property.
Alloy. A mixture, produced almost universally by fusion, of two or more metals. Sometimes alloys seem to be chemical compounds, as shown by their having generally a melting point lower than the average of those of their constituents. An alloy of a metal with mercury is termed an amalgam. An important application in electricity is the use of fusible alloys for fire alarms or for safety fuses. German silver is also of importance for resistance coils, and palladium alloys are used for unmagnetizable watches. An alloy of wrought iron with manganese is almost unmagnetizable, and has been proposed for use in ship building to avoid errors of the compass.
Alloys or what are practically such can be deposited by electrolysis in the electro- plater's bath. We give the composition of some alloys interesting to the electrician.
