Chemistry

Every moment of every day, chemistry plays a part in all we experience. This branch of the Helium network humbly attempts to illuminate the vast array of chemical knowledge, making it accessible to all. Let our site inform, inspire, and awe you with chemical wonders.
The uses of helium
By: Jacob Stanley
While helium is the second most common element in the universe, on Earth it isn't as easy to come by. Because it is a noble gas, it is unreactive and will generally not form compounds with other elements. When released into the atmosphere, most of...

Batteries are a nearly US$50 billion industry worldwide and are a necessary component of gadgets and toys worldwide. At the heart of the battery is the voltaic cell, an electrochemical system that generates an electrical current by taking advantage of the electron movement between different...

Helium (He), the second element in the periodic table has a very stable atomic structure. It is the second most common element in the universe with an abundance of 72,000,000 ppb by atoms. Only hydrogen is more common. Helium atoms have an atomic...

The Reverend William Gregor, an English pastor, discovered titanium (Ti) in 1791. Over 100 years later, Matthew A. Hunter, an American metallurgist, produced the first pure sample of this transition metal in 1910. Economic usage of titanium had to await the introduction of the Kroll...

Atoms are the smallest units that retain the properties of a particular element. Their interactions create the basis for chemistry and chemical reactions. They are made of positively charged protons in the nucleus and negatively charged electrons that surround the nucleus in the cloud. An...

At some point in every childhood there seems to be some commonalities. It seems the wish of most children is to exchange secret messages that no one else can read or understand. The idea of invisible ink is intriguing. It was not just for children...

Man has a long history with the reddish metallic element copper (Cu). The name of the element derives from the Latin word “cuprum” meaning “from the island Cyprus”. Cyprus supplied many of the ancient European civilizations with their supply of the metal. Copper...
The atomic second
By: D. Vogt
The atomic second is the precise definition of the modern unit of time known as the second, measured as the amount of time it takes an atom of cesium to vibrate, or shift between two ground states, exactly 9,192,631,770 times. - The...

In defining what is atomic mass, the combined weight of protons,neutrons and electrons needs to be considered - this constitutes the mass of an atom ( ma). The weight of all of these grouped together in a single atom when the atom is motionless...
Explaining the uses of the periodic table in chemistry
By: Alexius Tan
I first encountered the periodic table when I was a 7th grader. I was taught that the periodic table is a systematic arrangement of elements that exist (or discovered and recorded) on planet Earth. There are generally 3 kinds of information found in a cell...
