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.
Understanding the periodic table
By: John JS Smith
Have you ever looked at the periodic table of the elements and wondered what all the numbers and symbols mean? If you have, you are not alone. Many people are confused by the complex diagram. This article will explain some of the aspects of the...

Helium the second element in the periodic table after hydrogen is also the second most common element in the universe after hydrogen. High concentrations of helium are detectable within stars. On earth, however the noble gas helium is not such a common element as it...

Xenon, a relatively inert element, is one of the noble gases. Over the years, a number of valuable uses for members of the noble gas class of elements have evolved. Xenon is no exception with a number of commercially viable uses. The production of xenon...

When Dimitri Mendeleev first produced his periodic table in 1871 there were a number of gaps where elements were at the time undiscovered. To one of these gaps, at atomic number 31, Mendeleev assigned the element the provisional name of ekaaluminum. Four years later the...
Are there more than three States of Matter
By: Charles Fleyn
Yes, I believe, hell, it's been proven, that there are more than just the three basic states of matter. We have solids, which are easily recognizable, with molecules packed tightly together, liquids, which flow easily, containing free molecules, and gas, which contains molecules with enough...
Are there more than three States of Matter in our Multi Dimensional Universe
By: VampAngel1111
Besides the obvious facts regarding the most recently discovered fourth state of matter, explained in J.G.R.'s "Yes" article on, Plasma... Try to clear your mind and imagine for a moment the vastness of our universe, which the world's top scientific communities now...
What is matter?
By: Effie Moore Salem
Matter is a tangible, touchable substance that can be seen, touched, tasted, and felt. Matter is opposed to the intangibles that exist because of the interactions with other forces of nature. In educational studies, dependent upon the course of study, matter may have slightly different...
What is matter?

Matter: any substance which has mass and occupies space. It would seem that all physical objects would be matter and logically that the only things that could not be matter would be imaginary or intangible things. While that seems like a straight forward and uncomplicated...
