Dictionary » E » Electrons ElectronsElectrons stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called cathode rays or beta rays, the latter being a high-energy biproduct of nuclear decay. ![]()

Results from our forumTheories - Origin of Life... atmosphere is formed by radiolysis (the decomposition of molecules by radiation) [64]. Solar ultraviolet radiation and charged particles (ions and electrons) from the face of Jupiter's magnetosphere with the icy surface of Europa, splitting water into its components - hydrogen and oxygen. These ...

How does light energy get changed to heat energy?How exactly does light transform into heat--for instance, when sunlight warms up a brick wall? I understand that electrons in the atoms in the wall absorb the light, but how does that absorbed sunlight turn into thermal energy? How does light get transformed into vibrational energy?

Re: Charge transport through DNAI've read that the strand of DNA is conductive along the stacked bases, supposedly by electrons flowing through the pi orbital systems of the bases. It was proposed that the electrons move from one base to the next though the close proximity of the pi clouds when the ...

Why does chlorophyll always fluoresce in red?... weak red light causes chlorophyll's electron to jump one "energy level." Since blue light has more energy, it excites the chlorophyll's electrons even more: They jump two levels. (Ultraviolet has even more energy.) However, it's very difficult for the electron to stay at such high energy ...

Replication of Photosynthesis... part of the energy production in the plant itself. So, water coming from the roots gets hydrolyzed ( think Hydroxy, or HHO )and turns into H2 as electrons and O2 as gas. The O2 is breathed out, of course, but the extra H is used for extra plant energy. This explains why a RAIN forest is the lungs ...
