Diamonds Are Forever
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?

Use of diamonds
Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

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...

What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
Most Popular
Matter
Anything that has mass and occupies space.
Isotopes
Two or more forms of atoms of the same element with different masses, atoms containing the same number of protons but different numbers of neutrons.
Gas of rotten eggs
If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.
Oxidation Numbers
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
Specific Gravity
The ratio of the density of a substance to the density of water.
Cohesive Forces
All the forces of attraction among particles of a liquid.
Bonding Pair
Pair of electrons involved in a covalent bond.
Extrapolate
To estimate the value of a result outside the range of a series of known values. Technique used in standard additions calibration procedure.
Low Spin Complex
Crystal field designation for an inner orbital complex, contains electrons paired t2g orbitals before eg orbitals are occupied in octahedral complexes.
Coordination Number
In describing crystals, the number of nearest neighbours of an atom or ion. The number of donor atoms coordinated to a metal.
