Interesting facts about carbon
By: Elaine Sihera
Ever since it was discovered, approximately 3760 BC, the quality of mankind's life has depended on the properties of carbon. From birth to death, carbon has proved indispensable to our lives. It is in the air we breathe, the jewellery we wear, like the diamonds...

Carbon is known as the fundamental building block of life. It possesses the ability to bond with nearly every element, and it can bond with itself in a wide variety of ways. It is the fourth most abundant element by mass in the universe, the...
The newest elements on the periodic table
By: Brian Dodson
The periodic table, developed initially by Mendeleev in 1869, organizes elements into a remarkably valuable framework to classify and organize many types of chemical behavior. Generally speaking, elements in vertical columns have similar chemical properties. The table has found wide application in physics, biology, engineering...
What are Ven der Waals forces?
By: Sherry Horton Blake
What do these two things have in common – the amazing ability of the gecko to stay attached to a window with only one toe and the ability of a spider to stay on the ceiling? Give up? Well, the answer is amazing forces called...

An element, in chemistry terms, is a substance that cannot be reduced to simpler substances by chemical means and such elements are made up of atoms which are the smallest particles that retain all the chemical and physical properties of the element. Atoms themselves are...
How to determine the concentration of substances in a diluted solution
By: Luana
What is a dilution? A dilution is a reduction in the concentration of a solution. This will include a stock solution (solution to be reduced) and a Diluent (reducing agent eg distilled water). To calculate the new concentration of a diluted solution one must KNOW...
Understanding the law of conservation of mass
By: Elaine Sihera
The law of conservation of mass, which is a central theme of chemistry, is one of the first conservation laws to be discovered. It was established in 1789 by French chemist, Antoine Lavoisier, who is regarded as the father of modern chemistry. A gifted public...

Conservation goes beyond plastic bottles and aluminum cans. In the world of science, everything from energy to matter is governed by some law of conservation. And one of the most fundamental concepts in modern physics and chemistry is the law of the conservation of mass...
How the periodic table is used in chemistry
By: Luke Buffington
The periodic table of the elements is a visual representation of all 118 chemical elements. For the uninitiated it often appears to be an useless jumble of undecipherable numbers, letters, and symbols. However, for those who have learned to understand it, it is an invaluable...

The green chemistry movement started with the ban of phosphates from detergents. Then consumers demanded that detergents perform in cold water. Consumers are also purchasing washing machines that use less water. Unfortunately, consumers soon discovered that while phosphate free detergents saved aquatic systems from excessive...
