  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

Thermonuclear Energy

The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity. In these processes a small amount of mass is converted to energy according to the relationship E = mc2, where E is energy, m is mass, and c is the speed of light.

Gamma Ray

High energy electromagnetic radiation. A highly penetrating type of nuclear radiation similar to x-ray radiation, except that it comes from within the nucleus of an atom and has a higher energy. Energywise, very similar to cosmic ray except that cosmic rays originate from outer space.

Isomorphous

Refers to crystals having the same atomic arrangement.

Linear Accelerator

A device used for accelerating charged particles along a straight line path.

Salt and its use in everyday life

Cooking salt is a product that is available in every kitchen, and it’s not as simple as it seems. The history of this product shows that it was valued like gold.

Electrode Potentials

Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.

Electronic Transition

The transfer of an electron from one energy level to another.

Le Chatelier's Principle

States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it.
If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.

Contact Process

Industrial process by which sulfur trioxide and sulfuric acid are produced from sulfur dioxide.

Alums
