Alloying
Mixing of metal with other substances (usually other metals) to modify its properties.

The law stating that a pure substance will always have the same percent by weight. Different samples of a pure compound always contain the same elements in the same proportions by mass.
Composition Stoichiometry
Descibes the quantitative (mass) relationships among elements in compounds.

The dispersing medium of a solution.
Covalent Compounds
Compounds containing predominantly covalent bonds.
Substance
Any kind of matter all specimens of which have the same chemical composition and physical properties.

A unit of energy in the SI system. One joule is 1 kg. m2/s2 which is also 0.2390 calorie.
Valence Electrons
Outermost electrons of atoms, usually those involved in bonding.
Group
A vertical column in the periodic table, also called a family.
Resonance
The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.
