    Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?

  • The most expensive metal in the world

    Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.



Most Popular

Valence Electrons

Outermost electrons of atoms, usually those involved in bonding.

Dipole

Refers to the separation of charge between two covalently bonded atoms.

Absolute Zero

The zero point on the absolute temperature scale, -273.15°C or 0 K, theoretically, the temperature at which molecular motion ceases. The concept of an absolute zero temperature was first deduced from experiments with gases. When a fixed volume of gas is cooled, its pressure decreases with its temperature. Absolute zero physically possesses quantum mechanical zero-point energy.

Fast Neutron

A neutron ejected at high kinetic energy in a nuclear reaction.

Saccharate

A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.

 

Nuclear Reactor

A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.

Square Planar

A term used to describe molecules and polyatomic ions that have one atom in the center and four atoms at the corners of a square.

Nuclear Binding Energy

Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.

 

Downs Cell

Electrolytic cell for the commercial electrolysis of molten sodium chloride. For further information see Electrochemistry or Fuel Cells.

Electrophoresis

A technique for separation of ions by rate and direction of migration in an electric field.
