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.

Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

Exothermicity
The release of heat by a system as a process occurs.
Curie (Ci)
The basic unit used to describe the intensity of radioactivity in a sample of material. One curie equals 37 billion disintegrations per second or approximately the amount of radioactivty given off by 1 gram of radium.
Aldehyde
Compound in which an alkyl or aryl group and a hydrogen atom are attached to a carbonyl group and a hydrogen atom are attached to a carbonyl group, general formula, O-R-C-H
Avogadro's Number
The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.
Reverse Osmosis
Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.
Hydrogen-Oxygen Fuel Cell
Fuel cell in which hydrogen is the fuel (reducing agent) and oxygen is the oxidizing agent.
Electromotive Series
The relative order of tendencies for elements and their simple ions to act as oxidizing or reducing agents, also called the activity series.
Chemistry is a familiar school subject
Everyone liked to observe the reaction of reagents. But few know interesting facts about chemistry, which we will discuss in this article.
Fractional Distillation
The process in which a fractioning column is used in distillation apparatus to separate components of a liquid mixture that have different boiling points.
Zone Refining
A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.
