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.
How the periodic table is used in chemistry
By: Ramona Taylor
When a layperson looks at the elaborate Periodic Table of the Elements, he or she may think it looks like a game of Spider Solitaire; It's clear that the chart has nothing to do with cards or insects! To hopeful chemistry students, it is a...
How we benefit from chemical engineering
By: A.L. Lovern
Chemical engineering deals with physical science, life science, and math. It is the process of converting raw chemicals and materials into more useful forms. Chemical engineering not only deals with converting materials, they also strive for new material and techniques such as fuel cells and...
The chemistry behind the explosive mixture of potassium chlorate mixed with sucrose
By: Glen Brizius
This makes an excellent science demonstration for high school students when performed by a trained adult professional. Potassium chlorate (available through most chemical suppliers, such as Sigma-Aldrich - www.sigmaaldrich.com) is a white solid and perfectly safe to handle under normal conditions. Potassium chlorate...
How isotopes are used
By: Elaine Sihera
Isotopes are two forms of an element that have the same atomic number but different masses. This is due to the element having a fixed number of protons but with varying numbers of neutrons. The existence of isotopes can be understood by reviewing the structure...
What is chemical distillation?
By: Alexius Tan
Chemical distillation is a process whereby a homogeneous (meaning only one solution phase) solution mixture consisting of 2 or more chemical species are attempted to be separated. Students learn from high school science that distillation is a physical process, meaning there is no chemical reaction...
The newest elements on the periodic table
By: A.L. Lovern
The periodic table is a display of the chemical elements. It was first invented in 1869 by Russian chemist Dmitri Mendeleev. Over time the periodic table has been refined and extended due to the development of new elements. The periodic table classifies, and compares many...
Green chemistry: Adhesives
By: Glen Brizius
Green chemistry is dedicated to a series of ideas. Pollutants should be minimized. Whenever possible, toxicity should be avoided. "Feedstocks" (precursor materials / chemicals) should be cheap and readily available. The finished product should be comparable to current items on the market, so as to...
How to write chemistry lab reports
By: Glen Brizius
Chemistry lab reports - from the simplest high school experiment to cutting edge research in a University or Pharmaceutical company - shares certain attributes that must always be present. The degree to which the guidelines are followed varies depending on the "seriousness" of the lab...
How to get kids interested in chemistry
By: Susan Kristoff
Chemistry happens all around us every day, and can be used to explain many questions about the world that kids ask. Chemistry is a great subject to expose kids to because of the dramatic demonstrations and experiments that can be performed. Many experiments are safe...
Chemistry science fair projects: Carbon sequesteration
By: Susan Kristoff
Carbon sequestration is a hot environmental topic that can be translated into a science fair project topic. Scientists are looking for methods to reduce the effects of carbon dioxide on the environment by the "greenhouse effect" by reducing the amount of carbon dioxide in the...
