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 characteristics of an atom
By: Joshua Horn - 257112
An atom is the smallest unit of a particular element that still retains the properties of that element. The various characteristics of an atom give rise to its chemical properties, or the way that it interacts with other atoms. These characteristics include atomic number, mass...
Atoms: An overview
By: Joshua Horn - 257112
Atoms are the smallest units of a particular element that still retain all the properties of that element. The basis of chemistry involves the interactions between atoms. To be more specific, it involves the interactions between the positively charged particles of the nucleus, known as...

An atom is the smallest unit of a particular element. The basis of chemistry comes down to the interactions between atoms. More specifically, it involves the interactions between the positively charged particles of the nucleus, known as protons, and the negatively charged particles, or electrons...

Atoms are the fundamental unit of the matter we observe and interact with. The basis of chemical reactions is the interaction between atoms. More specifically, it involves the interactions between the positively charged particles of the nucleus, known as protons, and the negatively charged particles...
The chemical properties of helium-5 (He5) and its potential usefulness
By: Brian Dodson
Helium is a monatomic inert gas that is the second least reactive element in nature. (Neon is still less reactive.) It is also one of the least complex elements, having only 2 protons in its nucleus. Helium's 2 valence electrons reside in a...
Chemistry science fair projects: Optical rotation of different chemicals in solution
By: Ernest Capraro
By middle school, most students are aware that prisms can bend light. It isn't until high school physics that polarization usually gets discussed, and even then only in basic terms of polarizing filters and intensity. This is a chance to explore how certain chemicals interact...
Chemistry science fair projects: Evaluating water purification techniques
By: Ernest Capraro
INTRODUCTION Water purification is an important technology. It has applications around the globe, for every person needs and deserves clean water to drink, be it on a camping excursion, recovering from a natural disaster, or simple daily living. There are many ways by which water...
Chemical properties of noble gases
By: Jade Twits
Noble gases could possibly be the most 'perfect', yet least interesting elements out there. You won't see any fancy fireworks or reactions from them. In fact you might not see anything at all when you look at one - because they are nearly always gases...
The basics of redox reactions
By: Mishra Planeswalker
Redox reactions occur every day in the world around us. They may be subtle, such as a common breathalyzer test, or have catastrophic consequences such as the burning down of a building. They may be spontaneous (and happen instantly) or non-spontaneous (and happen over...
Plasma Aurora Borealis Electric Magnetic Solid Liquid Gas Matter Conduct Lightning Sun Northern Ligh
By: Jerges Cervantes
The simple answer is Yes. The three normal states of matter are easily recognizable as we are aware of them each and every day. Solids are probably the most easily recognizable form of matter to us. Solids are created when molecules are compressed together, giving...
