charged subatomic particle in the baryon family having a
mass 1,836 times that of the electron. See table at
subatomic particle.
Rare elements: Any of the elements
57-71 it is primarily a rare, not easily found
element
Alloys:. A homogeneous mixture or
solid solution of two or more metals, the atoms of one
replacing or occupying interstitial positions between the
atoms of the other: Brass is an alloy of zinc and copper.
The relative degree of mixture with a base metal;
fineness.
1. To combine (metals) to form an
alloy.
2.Something added that lowers value or
purity.
3. To debase by the addition of an
inferior element.
Electrons:A stable subatomic

from their ores, purifying and alloying metals, and creating
useful objects from metals.The study of metals and their
properties in bulk and at the atomic level.
Actinide Series:The science that
deals with procedures used in extracting metals from their
ores, purifying and alloying metals, and creating useful
objects from metals.
The study of metals and their properties
in bulk and at the atomic level.

extended or shaped by beating with a hammer, or by the
pressure of rollers; -- applied to metals.
