One may ask the question, "Do atomic nuclei have internal electron orbitals having similarities to those believed to exist in molecules? A quick answer could be, "Why not? There seems to have been little attention given to the idea of there being atomic orbitals in...

What exactly is helium 3 and how is it created?Normal helium has 2 protons and 2 neutrons in its nucleus, giving it anatomic weight of 4. Now, if you kick out one of neutrons, you gethelium-3. This happens once in a while in very...

A photovoltaic cell is typically comprised of two semiconductors, most often in the form of thin films sandwiched on top of the other, where light of a particular energy excites electrons in one layer which are then collected by the other. An understanding about how...

In the late 1890's physicists were conducting experiments with cathode ray tubes. Cathode ray tubes are sealed glass tubes that have wires embedded in them, so that electricity can be passed through the tubes. If the air is pumped out of a tube, the...

Fuel Emissions: studying the differences between petroleum and biodiesel exhaust emissionA growing concern over the environmental effects of diesel and diminishing natural resources has lead to the development of biodiesel. Biodiesel has promising potential as eventually replacing most of the diesel used in automobiles. Currently...

Some people think acidic, means corrosive. This is not entirely true. Yes, the more acidic a solution is, the more corrosive it can be. But, bases can be corrosive to. The acidity or basicity of a solution is determined by the pH scale, or also...

Did you know that everything is made up of tiny particles called atoms? Two or more atoms chemically bonded together form molecules. Every Element consists of molecules. Everything in this world is made of elements. Elements bond together to form compounds. Did you know that...

Electro-deposition, or electroplating is a common and effective solution to prevent the effects of corrosion on different sorts of metals. Basically, it is when an outer layer of elemental metal (or less commonly an alloy) is put over top of a specific object by using...
