Nitrogen
Think Energy Nitrogen The gas nitrogen (N2), composed of molecules of two nitrogen atoms, occupies 78% of the Earth's atmosphere. It is colorless, odorless, and tasteless. Nitrogen is as important as it is common. It's essential to the nutrition of plants and animals. Nitrogen ...

Earth's magnetic field. These charged particles collide with oxygen and nitrogen atoms, and the resulting ions (atoms charged by the loss or gain of electrons) emit radiation at wavelengths ... outer electrons from their parent atoms. Eventually, the atoms get back together with their lost electrons and give up energy in the form of light. In particular, when nitrogen atoms are ripped apart ...
